Thanks

[SkidMark]

Well i figured I would give you all an update.. The car runs fantastic with the mercedes eaton supercharger!!! I got together with Jake from classic daily, best guy ever!!, and we decided to change DME's to a e30 from a e36. This enabled me to run his turbo tune for the m42. He scaled back his tune as I am running less boost and smaller injectors. The car runs great, idles perfect, and pulls HARD!! Its running about 7 psi boost at 6500 rpms, and is a solid 14.7 afm. Havent gotten it on the dyno yet but its really really fast!!!!  THANKS JAKE!!! You da Man!!!  Skid

Hi Skid
Why did you change the dme, to e30 from e36? Disa
Cheers Rohan

Hi darky! Since I had to build a new manifold there is no disa valve. Also, i couldnt find anyone that had a tune or could write a tune suitable for boost applications in an e36 chip. Would have loved to use an e36 dme because of its knock detection but it just didnt work out. I guess the e36 is a completeley different animal when it comes to writing tunes. I am not a tuner by any means thats why I called Jake B. ... Skid

Hi Skid

I just thought that the disa in the e36 programming would be the pain.

That makes sense with regards to keeping knock sensors. I can't understand why e36 dme is that much harder to program. What's does 14:7 afm mean?

Be interesting to see your dyno curve and your air fuel ratio curve.

Cheers Rohan

[SkidMark]

14.7 afm, the air to fuel ratio.

I hope the 14.7 refers to idle AFR only. That's far too lean for higher rpms/loads

[SkidMark]

Yea Collin thats at idle. Its around 9.8 to 10.2 w.o.t. ..thats a little richer than I would like but ok for today. Jake burned me a leaner chip I havent tried yet but I will give it a shot possible today....Skid

Wow! Very interesting!

I'm currently building a setup from a merc (m62) onto and m42 for my e10.

I really didn't think standard ecu would even be an option I've been looking at standalone!

Do you have any photos of your pulley set up? And sizes? And belt tensioning?

Are you planning to get it on the rollers soon? I'm not sure what sort of injectors to use yet also!

Also the bypass system? Have you used it or are you just running it under boost constantly? I've gone for a different set up with the manifold as I'm wanting to run an intercooler going I to a plenum as I was worried about tempratures
