The Project Pad

Nice work dave, How does it feel compared to the MTM chipset?

Car looks great! it just needs a set of RS2 or H1/H4 headlights.

Check your actual timing, but have you zero'd the timing through the software?

Id like to say It was my idea, and maybe it was, but it was the most logical solution to the problem. Im sure thats the solution they would have come up with whether I was involved or not.

So what is the actual problem, all these CQ and 90q running out there and all are fine above 2K rpm (including my own 4kq).
Is it the Motronic?

Thanks

I believe the statement was made is reference to running the 7A flywheel/reference pin while using a VEMS engine management ECU.

That's fine, but the sensor is the same so the signal should be the same... VEMS just can't see what Motronic/Hitachi can?

no the motronic only uses it as an initial trigger. If you snap off the timing pin while driving the car will continue to run until you turn it off (ask me how i know)

the motronic runs the car just fine martin. it does a great job of doing so and has been for 20 years. the MTM software worked great for what it was. but compared to the vems, which is programmable, its antiquated and limited. the possibilities with the vems are endless. the mere fact that its plug and play makes it fantastic.
If I were to replace the injectors, the motronic could not run the car right. it had the stock injectors running at 100 percent DC. It needed bigger injectors in a bad way.

everyone who has replaced their stock ecu knows the benefits of having the endless posibillities of a standalone. the motronic was old school through hole tech. vems is surface mount and up to date tech. much faster processor with communication that is lightning fast.

I like it Dave. as soon as I figure out the dett issue, I will feel alot better about mashing the throttle and not worring about the engine destroying itself.

We need to get together sometime. I want to drive the car and see how VEMS works.

so i couldnt sleep...4:44am and i read the thread. What happens next??? dett issue figured out?

so here I am brousing through the forum while at work and my project thread pops up.

yea, I believe it may be mostly handled by now. I dont get to drive the car as much lately since I dont want to drive it in the snow and road salt. not to mention god forbid it get hit by another retard that cant drive in bad conditions. the last tank of gas I had was the govt idea of a cleaner emissions fuel. they call it oxygenated fuel. just has up to 10% ethanol. not good for trying to tune for just plain 91oct. last weekend I filled up at another station I know of that doesnt have the "oxyfuel" and tiried a few full throttle pulls. after the car was warmed up completely I saw it was fueling what marc said it should. I plan on giving it another go in the next few days to see if it is corrected. Im not entirely convinced to be honest.

while I have the motor out to get balanced I had planned on sending the ecu back to marc to have him throw it in one of his cars to see if he could recreate the problem. Im not uber worried or all that impatient honestly since I dont drive the car in the winter anyway. I was hoping to get the motor done and a new clutch, new double sized atw innercooler built, tank relocated, different radiator installed, new aluminum front crossmember fabricated with reengineered snub mount, revamped suspension, volvo hybrid turbo to name a few things. but I have been a little short of funds anyway so it gets pushed until I feel comfortable I can do it financially.

I hope it turns out to be a fault with the computer as I dont understand how it could have been so difficult to tune this thing since marc has tuned so many others with this spec. I dont know, Ill cross my fingers. meanwhile Ill try to sell off some of my spare parts to try to fund this endevor. anyone want to buy an mtm chipped ecu and an 01e among other parts?

What kind of 01e and condition/etc? I could possibly be tempted. Beautiful car...I really need to look through your project thread now. :-)

Those seats you installed look fantastic! I went the Volvo hybrid route, but i did some modifications to it. If it comes back to me spec'd out like i wanted, i will include it in the write up and i will let you, Dave and Bimmerboy know who did this and for how much. Right now it seems unrealistic what this guy is doing, for so little money. I love your car, it really is one of the nicest i have seen, but i think thats the Utah standard for coupes now a days. Hope you get it sorted in a decent amount of time, but it sounds like with the rebuild coming and another turbo installed, this could be going north of 400hp at the crank.

Back to those seats, were did you get them from? I want to replace mine in the wagon (i have to in order to meet spec for the 200mph run) and those actually look DD comfortable. Over 800$?

thank you sir. Thank you for noticing. the seats cost just over a G, but with their brackets. if I were to do it again, I would just buy the sliders and make the rest. the seat brackets were too simple to have paid what they cost me. that would save you a small chunk. and they are very nice for DD. A very nice and wise investment I might add.

North of 400 may be a bit too generous. actually Im going for somewhere between 3 and 350 at the wheels. Im not greedy and I love the fact that its a KKK turbo that is just as reliable as the k24 or 6. just better. mine is a carpet cruiser that sometimes sees a few Autox's. it depends on the surface. I do have the 90sptQ for the serious days kick'n the cones around. It is a former first place H-stock national pro solo car. but its time has come to shtcan the v6 fo a 4.2

as far as standard for Utah, dont know. although we have a nice collection in the maffia here and vegas, Ive seen some real winners if you know what I mean. I believe the Mafia just takes extra special pride in our cars. we must keep up appearances mustn't we? I have just had my car a very long time.
