First OFFICIAL TWINCHARGED M20 BUILD

[Denny]

Denny, when i put a miller maf on my m20 on the dyno it wouldn't rev past 5k ish. Worked great with the stock chip. Ended up being an aftermarket CPS that i didn't know was on there. New OEM CPS and no more problems.

Interesting about the aftermarker CPS being crap...(noted) if I have to replace mine which is OEM... I know in my case I had the miller MAF and chip before going MS2 and never had a problem with the CPS (I had many others but not that lol) actually the only thing that changed from last year supercharged (a side from adding a turbo and injectors) was in fact the addition of MS2 which now Im doubting on my assembly..:(

Im going to go work on it today and get to the bottom of this..

if you don't have a stim I suggest getting one, it will save you so much time.

[whodwho]

He has a DIYPNP unit and no place to plug a stim into, I took an old engine harness and pigtail and wired it into terminals of the jimstim and you can plug onto the 55 pin connector of the PNP.

Shouldn't be the MS unit if it is running, but make sure the CPS is adjusted close(I have found that to be an issue many times) if you would like to email me your msq and datalog I can review it for any oddities - w h o d w h o @ c o x . n e t

I didnt want to bother you with this god know I did too much in the past while building the MSII unit..lol..

the log file is nothing big just me running around 1/4 throttle...tuning part throttle but am sending it to you right now!

thanks again my man!

[whodwho]

NP, that is what megasquirt is all about!

I did a ninja edit on you, make sure on the CPS gap I have found that to be an issue many times. 8^)

Thanks when it comes time to replace OEM all the way!

**** UPDATE **** UPDATE problem SOLVED it was the gab on the CPS :) thank you everybody for all your help I learned something new***


TEST DRIVE!!I would like to say that my hands are still shaking right now as I type this.....GODDAMNSONOFABITCH!! this car is BRUTALLY fast!! Went for a drive I cannot explain the brutal power and the responsiveness that boost comes online.

I dont have a video as I dont have anybody that can film it right now.... but here in a few words for now...

Driving along second gear at around 3000rpm 1/4 pedal...I slightly and I mean slighty give it a bit more and am sent back to my seat like as If I got hit by a train in the back...I loose all traction almost hit the sidewalk with people walking by thinking am some kind of crazy guy thats never driven a car before...LOL... I cannot imagine full throttle on this car...I just cant!! I think I went to far with the responsiveness.. maximum I hit was 224KPA only about 15PSI or so....as I let go of the pedal real damn fast....I think am making over 20PSI ...

I have been in fast cars before but this is just rediculous...am going to go calm down now....

[chance]

HELL YES!

NEED VIDEO! I would love to ride in that thing, but you arent too terribly close

[JCarp90]

boooooonnerrrrrrrrr

[straight6pwr]

in for the video

[kamotors]

Yay, video time:)

[TheTacoMan]

Pleassse post a video.

[akorcovelos]

great...now I need to buy a Turbo...thanks. Can't wait for the video.

About damn time someone did this! :hitler:

Sick project Denny! I thought of doing the exact same thing, but with an M50 non-vanos, and an HX40 instead of a 35r.

What gearing do you currently have? I would want super long gears to take advantage of the epic power curve! A G260 with 2.93s or a ZF320 with a 2.79 would be so much fun! :twisted:

Can't wait to see the videos, and how the tuning process goes! :D
