Mivec

[0dd0ne]

any one know how to change it via WARI?

Other then matt i mean cause hes obviously busy and i kinda need to know if its working before tomorrow and i want to be able to point this out to the tuner (he reckons its not being controlled by the adaptronic) tony you got any idea? jem? :confused:

will take an offers =P

[Jemjem]

The mivec was a pain in the ass........ It's a question that Matts got to answer, im not sure..... Sorry man...

[0dd0ne]

damn hey. well its going in tomorrow morning (i'm not leaving the place til its on the fucking dyno). i guess ill have to wing it.

[steel]

Is the MIVEC a continuously variable thing or is it just a binary on/off thing, like doesjust flatly open and close the intake valves a fixed 40 degrees later when on?

Can anyone please post some screencaps from the MIVEC in the WARI software?

The tuner doing my car has done 4 cyl turbo cars on Adaptronic but I think they have almost all been 200SX drift cars so just to arm me with as much knowledge as possible would be awesome please.

[0dd0ne]

ok just found out that mivec wasnt on. I told the dude to just apply the aux outs to vvt til it did something. Its aux 2. Now hes setting mivec up.

[ELEGNT]

so when will the tune be done this arvo? and u waiting there with him or picking it up later?

[steel]

Aux 2 = VVT eh - I guess that would be set up the same for all of the Adaptronic RColts. Good to know.

[0dd0ne]

i'm sitting in jem right now. Apparently a magna melted its wiring loom so they are shifting that off the dyno and then mine is going on. Tuner guarantees it will be done today. I'm not leaving til it is.

[ELEGNT]

have fun waiting round man. id be sitting in the car the whole time tyring to see wtf he is doing.

i want to see atleast 155kw mate

[Ayu452]

yeh mivec is control via adapt...n i believe it can do up to 32 degrees on the intake cam...
i remember we plug in some vvt values in the low rpm range then as boost comes on gotta reduce the vvt timing...helps with bottom end torque

[0dd0ne]

yeah home now. mivec wasnt setup at all, nor was it even selected on aux outputs. also the tuner was freaked the fuck out cause the cars running on wasted spark and not full sequential like it would from stock. reckons it will run higher boost smoother and the coilpacks wont be fried in 25000km. also apparently my spark plugs are fouled. it gong back in on the 25th of october for rewire, new plugs and a tune. ill probably be running a straight pipe by then aswell...

137.8 kw and 300ftlb of torque. This was apparently a conservative dyno.

Isn't the full sequential / wasted spark etc a software setting?

Makes me worried if mine might be set up that way too.

Edit: Could that have something to do with the ignition triggers, like somehow being triggered by the crank angle rather than cam angle so firing twice as often as needed?

[0dd0ne]

nah its hard wired. the tuner got on the phone to adap about it. they reckon it was "easier" or something. the tuner was like "if its sequential from factory, why fuck with it"

apparently makes the coils wear out twice as fast. oh and you can get past it by regaping sparkies (mine are at 0.6) to stop the ignition break down.

apparently to rewire to sequential all you have to do is run another 2 wires in the loom from the adap to the stock ecu. of course with our cars that requires removing the fucking airbox etc.

[steel]

Damn man, it seems like a very very small shortcut to take, the the point you question why they bothered.

That's another thing to get done then.

[0dd0ne]

yeah it seems really stupid. i dunno why they did it that way.

[daedalusjc]

because theres no advantage or disadvantage over sequential. In wasted spark the plug that is igniting the air fuel has a higher resistance thus drawing more current so the other alternate plug isnt under pressure thus has low resistance and minimal current draw. very negligible. It also burns off any unburnt mixture in the wasted cylinder. Coils burning out is also a myth. does your tuner live in the 1960's or something? It all has to do with the dwell time man. Low dwell time - less heat = longer coil life. Depends on how its set up. I trust adaptronics setup on all of this stuff and they wouldnt instruct installers to do so unless they knew it would be fine. put it in the same context as the clutch scenario. while in stock form the colt's clutch should last 100000km for example but with a 200% power increase the service life is now decreased to say 40000km. Same with ignition packs. At 12 psi the plugs and coil drivers perform flawlessly. At say 30 psi there;s expected to be a breakdown in the ignition system and a miss. Your increasing the cylinder pressures drastically thus creating a higher resistance and making the coils work harder to produce the same spark. Pretty basic. You cant expect the adaptronic to be able to work outside the scope of the factory parts when the load induced on them is nearly double.

Aux out was disabled when we were fault finding. It wasnt re-enabled once we found it was the kill switch.

IMHO the wasted spark debate is nothing but propaganda. They didnt install the ecu so of course there's extra money to be made by making claims leading you to accept having it rewired. I know i sound like a c*nt dude and im not having a go at you. It just really shits me the way certain businesses impose there own personal and unproven theorems for the sake of profit and not being able to get with the times. Maybe coils would have worn out 20 years ago but we've moved ahead with production and manufacturing processes

Yeah agree on that....... any reason to get more money out of you they will....

[0dd0ne]

yeah fair enough matt. i got some time to fuck around with the car anyway so ill see what happens and how she runs. im pretty fucking stoked with 406nm though.

btw adaptronic sound like they are in love with you, the tuner called them today and they were raving about how awesome you were lol

[0dd0ne]

guys i was just looking on the forum at dyno results. it seems like ive got nearly 100nm more then anybody else, whats the go with that :S

[Corosith]

That's a hell of a lot of torque for a 1.5 litre, put a lot of V8's to shame!

[daedalusjc]

wait oddone wtf? that torque is monster dude

[daedalusjc]

no shit hey. that cant be right. thats stump pulling. you can drive around in like 5th everywhere. love to see a time from the drags with it tuned as is

[0dd0ne]

yeah, the more im sitting here the more im like "is the printout wrong?" Even the torque curve is pretty flat once it hits 70kmh.

i know sitting in the car and putting my foot down it feels pretty fucking epic but... yeah shit it still sounds like way to much. fucking xr6s (non turbo) put out less then and they are 4 litre.

and i agree about the drags matt,, but i need an lsd and some serious suspension work to get the traction

[skyrex]

Yeh that torque reading I bet wasn't calibrated correctly at the time. I've got a feeling that alot of dyno's need independent runs to calculate kw and then tq (can't be done in the same run)
My lancer on the dyno with its monstrous 98.8kw atw supposedly pulled 300tq - 80tq+ more with only a CAI. LOL

[runuts]

I'm not sure how many people are aware, but that is not engine torque that is read on the dyno. Its tractive effort. It includes the torque multiplication factor of the gear ratios etc. Divide it by the final drive, in the gear you are in, and you'd be on the money.

As for the wasted spark, I would run sequential. It makes no sense to change it to wasted spark. It will load the coils harder, as there is far less time between firing cycles(dwell adjustment or not). Wasted spark does work fine, but sequential is superior.

[skyrex]

Does anyone know if the above mentioned gear ratio can be input into the dyno application for it to do the maths for you?
Then give you accurate torque figures/plotting on graph? I know alot of people don't know what their ratio numbers are but just as an instance of if you asked the dyno guy to do it?

Surely it's possible for a dyno to work that out for you so it plots an accurate graph, or at least some of the types of dynos out there...

[Turbo_Tim]

Yep like has been said, dyno torque figures are somewhat irrelevant.

Don't worry if you think the power figure is a little low, dynologs have a reputation for being a bit on the low side of life.

[0dd0ne]

not sure how irrelevant it is though. it certainly pulls like a fucking truck now. i was completely shocked at the feel after getting in.
