The 15 Y/O Turbo M42 Build Thread (Now Holley EFI Terminator X Controlled)

[Dj Buttchug]

What ignition timing are you running? I am running waaay dialed back timing on my DASC but it isnt intercooled. I need to have it professionally tuned.

you shouldnt be taking time away you should be adding time, and only a small amount.

what is your set up?

[e304me]

Standard DASC setup. I dialed it back because once it gets heat soaked it pings every now and then. Havent heard is knock at full throttle obviously but I still dialed it back. AFR is good. Supposedly the setup was bulletproof for e30s but they dont have knock sensors like the e36. I really wish it was more possible to add an intercooler.

Try some colder spark plugs. Just becasue the afr is good doesnt mean you cant still get pre ignition.

I think you could get away with no intercooler if you got a better tune. Post your msq file and maybe I can help a bit more

numbers are looking good! :up:

Not excited to see that our manifold/tb is even more worthless than I thought...

same. its even worse to hear the car choke out up high. It wants more so bad but its just not happening with the stock setup. Its not so much the intake as it is the dual plate style throttle body.

I am running a step colder from stock.

I am not using megasquirt I am tuning the stock DME with ostrich.

this is your problem then most likely how much boost? and how are you delivering fuel? RRFPR?

[e304me]

7-8lbs of boost. I got rid of the RRFPR and tuned the car for 36lb (I think?) injectors. AFR is locked around 12 at full throttle, could probably lean it out a touch but its a safe tune. Stoich during part throttle/cruise.

[Dj Buttchug]

you could try another step down in plugs. i assume its 91 pump right? Its real hard to say whats going on without seeing some tables. 12 is safe under load though.

[Schnitzer318is]

^12 under full throttle? Hmmm... I've been tuning for 11 at WOT @ full boost. Might have to lean it out and gain some more torque.

PS: I love and hate your thread Buttchug. Makes me want to keep my turbo m42 forever. But unfortunately it has to go soon...

[Dj Buttchug]

i promised a vid so here it is. its super shitty. my gopro is dead... Ill post a better one when I get time. Enjoy. this is exactly 1 bar.

[Dj Buttchug]

and heres another of first and second up a hill. no traction at all once it builds full boost

[MF DOOM]

I was just thinking. Youve got like 1000cc+ injectors, right? Why not go e85? Could easily gain some good power by doing so.

Also, I copped a pc so I should have solidworks up and running soon.

Bitchin. Ill pm you some more ideas Ive got soon!!

If you need some parts modeled up let me know. I have SW at home and use PRO/E at work. More than happy to help a M42 project!
