I have been in contact with the guys at MRT in Sydney. They have told me they will have a tune for the Colt in 2 months.

Well, me & steve-b has volunteered both our cars to MRT when they first show interest in Ecutek our ralliart at the very early of the year. They kept telling us that its out soon.....but still see nothing :( Hopefully, they do have a tune soonish. I seriously want to get rid of engine light restriction :mad:

They are not using anyone's car as far as i know. From what i was told, they will be initially use a euro CZT's mapping and modify from there. CZT in euro has the same engine as our RColt. And the Ecutek isn't out in euro yet for their CZT. Hence, we are really just waiting for CZT's tune to finish before they can work on our rcolt. Technically, the mapping will be identical.

I work around the corner from MRT. I have never seen a colt in there. Perhaps if I can get a list of people who would do the tune I can drop it in there to them. Maybe we should start a new thread with a list of people ready to put their money down?

BTW I pick up my Colt next weekend!!

lovecolt

12-07-2007, 11:41 PM

I live near to MRT :D And i know of a silver rcolt that hangs around there too. Which color u getting? Should meet up when you got yours ;)

I think it will be a good idea to organize a group chip tune when the tune is available. Because as i said, its not up to MRT at the moment to get the ecutek ready for our car.

I would have preferred black but I am getting red (which was my second choice) However for 19K who cares what colour it is!!! Definately keen to meet up and to go for a "cruise" though galston gorge and mcCarrs creek

I have more news from MRT

"Hi Nathan,

We will be able to retune the Colt ECU's in 2-3months. At present we have no prices available for expected tuning costs. Thanks for your offer of a car but we have already organised a test car, if we require another car I will let you know.

Regards,

Julian Caddell

Hi Julian

Thank you for your response. Having searched around the net I am led to believe that an ECUTek map won't be available for at least another 4 months. Can you please confirm or deny this claim? There are a number of people waiting and willing to take on this remap when available from the rcolt.com forums. Do you have an indication as to the price for the tune at this stage? Lastly do you have a vehicle to carry out your testing on?

lovecolt

13-07-2007, 09:37 PM

i'm just interested who's rcolt will be the test car :)

Wolfe

Hi RColt members. This is Wolfe, a moderator from the Singapore DC Colt Club. Would like to update you a bit regarding ECU Reflash for our Colt Rs. This particular method of tuning is now available in Singapore and I believe my car is the 1st in Singapore to go through it. Due to the agreement I have with my tuner, details cannot be release yet.

The results of the tune and dyno are as follow:

1) 217BHP/317TORQUE on crank @ 0.9bar Boost
2) 223BHP/328TORQUE on crank @ 1.05bar Boost

Noticeable Differences:

1) Car is ultra responsive. A light tap of the gas pedal will send you car surging forward. A little more pressure and maximum boost is achieved throwing you backwards. To be frank, I dare not apply too much pressure because I firmly believe our stock brakes ain't good enough.

2) Good Response from car even though you are in the incorrect gear. The noticeable differences for example are when you try to move off on 2nd straight after clearing a giant hump. Car will tend to jerk a bit but this is totally gone.

3) Low End Loss due to exhaust and open pod modifications have been almost totally eliminated. I get really good power even at low end with minimal force on the gas pedal.

4) Turbo lag is almost totally minimized. My tuner was a bit surprise at the results as well but he is convinced that this is because our stock turbo (TF035) is relatively small.

5) CEL issues commonly attributed to installation of Boost Controller, overboosting and incorrect A/F ratio is totally gone. I have tried to whack the pedal at the wrong gear to induce a sudden build up of boost and drop gear from 5 to 3 at ridiculous speed for testing purporses and no CEL.

I will be testing the car tonight at a private drag event to gauge the power gains. Stay tune.

Note: Bro lovecolt: Is it possible to share the contacts of your preferred local garage so that I can get my tuner to contact them to offer more details into his method of ECUReflashing? I hope to be able to offer an alernative for non-Singapore Colt drivers when it comes to tuning to thank you all for the help you have given to my Singaporean friends so far.

killercolt

Sounds like the reflash is well worth the money a very good result.

16-07-2007, 08:08 PM

thanks mate its good to see some numbers that someone has got, gives people a bit of an idea what to expect

and am i to assume the power is at the wheels? it so thats going to be one very fast little car

putty_sydney

16-07-2007, 08:20 PM

Hi Wolfe

The guys here in Sydney looking after ECUtek are MRT. Their website is www.mrtrally.com.au. The contact there is Julian.

There is a tune for the czt in europe by unichip. Don't know if this will work on our ralliart model?

Rdster

16-07-2007, 08:27 PM

1) 217BHP/317TORQUE on crank @ 0.9bar Boost
2) 223BHP/328TORQUE on crank @ 1.05bar Boost

'On crank', would be at the flywheel,not the wheels....correct me if I am wrong.

oh yeah didn't read that, thats massive amount of effort to take the motor out to do a dyno run

Wolfe

22-07-2007, 12:02 PM

The results for my dyno are done on flywheel (crank).

|2colt: My car is not stock. I am running a HKS EVC boost controller, upsized straight thru exhaust system, HKS open pod with CAI setup and a EVO 9 MR metallic dump valve which holds boost better than the stock plastic one.

putty_sydney: It will be good to get your tuner to contact me @ my email so that I can link him up with my tuner.

UniChip is a piggyback ECU management system. The big difference between the UniChip and a ECU Reflash is that the UniChip will utilized one single map to control all your different map settings in your stock ECU. The ECUReflash tuning meanwhile will correct each of your map to ensure maximum gains under different conditions. The main reason why I selected ECUReflash is because of its abillity to up power and to maintain excellent drivabillity under any conditions. The results are obvious to me.

Just spoken to Brett Middleton of MRT. He advises that EcuTEK is delayed as they are currently seeking a volutneer to borrow the ecu and ship it over to UK for development. He said he might have one to ship over next week. Either way, i have offered him mine if he needs one. Personally, i will take EcuTEK over Unichip.

What's the method for being able to remap it?

Yes, I am aware that no one is doing Original ECU Programming for Colt in Europe. In fact, with all the Tuners contacts I have all over the world, none of them have managed to do it. That is why I dare to say that I am the first in the world to have done it successfully.

I am using my own tools developed together with my Korean partner. We are able to read and write the original 8503 chip ECU and I use an Italian Software to do editing. Afterwhich, we do the checksum ourselves too.

If anyone is interested, just send your ECU to me and I can do a boost, speed cut and push up the REV limit to 7200. If you are able to provide RON detail and climate condition to me, I will be able to do a decent tune too.

what kind of time frame and cost are you looking @ Harmony ? also do you offer any other parts or tuning for the colt, if you get enough interest we might move you to the vendors section you can have a set place for your enquiries.

Wow, I am impressed by your offer. :)

I am able to finish an ECU in about 2 hours. I think you will have to estimate the turn around flight time for your ECU. For Singapore, freight and courier is extremely fast.

I charge S$1000 for each tune, approximately US$650.00 (freight charges not included).

27-09-2007, 10:10 AM

it isnt that funny...lol. mitsyman said when he changed the exhaust and looked @ the a/f ratios that were standard he said the car was running very very rich. Thus if you leaned it out, with or without the addition of an aftermarket exhaust, would you not get more performance and better fuel economy ?

ShortShift

27-09-2007, 10:22 AM

No the engine will start pinging and you'll ruin your bottom end, and possiblly warp the head (depending on what it's made from)

27-09-2007, 10:40 AM

not sure what you are talking about, or what your on. if a safe a/f @ 3000rpm is 11 and the colt is 15, then you could put it down to 13 or 12 with no problems. and if you did that across the rev range where mitsyman said the a/f we overly rich, then you would be using less petrol with more performance.

Stoich is approx 14.7 making 15 ever so slightly lean. Yes you could defiantly go to 13 or 12 and run a richer mixture but isn't that the opposite of what your proposing

I'll have to have a chat to Jeff from the speed lab here in adelaide, he may be able to do an ecu remap. He normally specialises in nissans etc. but I do know of many toyotas he has worked on over time, so we shall se if he can do something with the colt

Fantastic, I would have thought there would some capable tuners in Adelaide, does anyone have an opinion on the unichip (piggyback computer) as a method of tuning our cars, or would the mitsi computer be too hard to work with?

can you write a small bit about what changes you do. Ie does it lower fuel consumption, higher boost, boost cuts. What is the full extent of mods that you do. to give us a better idea.

To date, I have tuned 6 Colt (3 Manual and 3 CVT). Generally, I will remove the speed cut, boost cut and push up the rev to 7200rpm. I can also raise the boost limit. For those that I remove the boost cut, the owner will have to install a boost controller to manage the boost.

For CVT, my recommended boost is 0.8 bar, although I will tune the engine up to 1.0 bar on the dyno.

For Manual, my recommended boost is 1.0 bar and I tune it up to 1.2 bar.

Depends on the set up of the engine, there are some with totally stock engine, intake and exhaust and some with header, down pipe, exhaust and air rams upgraded.

Generally, those with their intake and exhaust upgraded, I found that the AFR too lean to my liking and I have to rich it. There is also 1 that I did not change the AFR as it is beautiful. My target AFR is based on the power output and not fixed to a range as some of you are discussing here. The general range is about 11.2 - 12.2 lambda at the high end. At this lambda, I find that the power output is at the max zone and the ignition can be advance quite a bit (7 - 15deg) without pinking.

I have a Colt with pinking problem even when I was running the base graph on the dyno. For that, I recommended him to install a fuel pressure regulator and it solved the pinking problem.

This is my latest result: Manual with intake rams upgraded.

http://i17.photobucket.com/albums/b96/HarmonyMotor/SGU1716Tb4After.jpg

Lower Green = 0.8 boost
Upper Green = 1.0 boost
Blue and Red = 1.2 boost

can you please help me with something. Does the colt have a speed amd rpm wire from the ecu ?
Because ALOT of people are running the hks evc which i know use's those wires, but from the workshop manual we have, it says that all data is sent over the canbus system and thus there is no speed or rpm wire. Can you take a pic or explain ( if you know ) which wires we can splice into please.
Or do you only need speed or just rpm to run the evc ?

What's this dr drift? In terms of retuning what do they really do thouhg, do they include dyno and road tune for the whole procedure or just some simple fiddle around with the ignition timing and air/fuel ratio. I will be extremely interested about this Dr Drift if it works out. Otherwise i have been trying to find alternatives.

best case would be if MRT did a package for them... they cover the manufactures warranty on their kits... am eyeing from a distance the XB for me forester for just that reason... and they were looking into the colt.

To make it clear, MRT might only provide warranty on their work, but 100% definitely not for Mitsubishi's warranty.

GM Grey

03-10-2008, 05:11 PM

Bascially, with modding you are always running a risk of voiding warrenty. If the dealer really want to be shitty, they will find any reason to avoid having to fix your car unless it is a major problem like the clutch noise. Otherwise i have already prepare voiding my warrenty anytime when there is ECU mod availiable. Where is this Dr Drift anyway? i thought they situate Melb. If they have a work shop in Syd, i don't mind bringing my car up there for them to use mine as a test car. But if they are down all the way in Melb, i would have a hard to explaining to my miss why the car is going all the way to Melb.

What is covered?
The Lifetime Warranty covers all parts and labour of components supplied by MRT or directly affected as a result of the services performed or components fitted by MRT.

Therefore, Mitsubishi will not honor any warranty with the direct affected area of the mod you installed. But MRT will. So, i stand corrected ;)
