Unichip and larger injectors thread
- Thread starter JDM Sam
- Start date
Wait, so you tuned a larger turbo with the 440's? And there were no issues?
Hopefully that means it'll be fine for the stock turbo with the 440's. Have you ever tuned a Unichip for larger injectors in person before, Sam? What other mods did the MSP have? Cause if it's similar to my setup, I might just send my Unichip back to you again and forget about getting it done locally.

i had my unichip dyno tuned up here in canada and it ran awesome
i had a similar setup to discreet speed
i was running:
T3/T4 turbo setup,
custom 3" downpipe with electronic cutout (tuned it open and closed)
3" GHL TB
440cc injectors
FMIC
and on idle and cruising i was running perfectly at 14.7

No no dyno numbers, Sam tuned it at about 1.2 bar of boost.
Sam?

i was dyno'd at 226whp at 8psi and open dump
then i turned the boost up to 10 for the whole summer... then turned it up to 12psi which lasted about 3 weeks... but it was fun
so if i use the whole rule of 1psi=12whp then i should have been up around 274ish... give or take haha. i dont know the exact numbers at 10 or 12 but i know that 12psi pulled pretty damn hard and was completely different then 8
now im in the process of rebuilding the engine and starting a whole new turbo kit from scratch again.

^^^ wow i bet 17psi (1.2bar) would pull pretty freakin hard... ill see what thats like soon
^^ Did you have any troubles at 10psi? I'm still trying to figure out how high I want to set the boost level when the time comes. I'm wavering between 9 and 10. Definitely nothing higher than 10, though .. My MSP is all I've got, I'd be walking without it!
Thanks for the dyno info, though.

10psi was great all summer long.. soo much fun to drive and perfect power for the car... but warning: once you up the boost, it is oh so hard to not keep going up haha
Nope his was the first non stock injector MSP I did. I was going to do it on mine, but I just put it off since I didn't care anymore with my Haltech E8 sitting around. There aren't many active MSP that are modded with full bolt ons where I can map one off of.
I've considered flying out to a meet in each area this summer to come tune a group of cars at a time and get a lil vacation time in at the same time. I'll make a thread and see what happens.
I think it worked out pretty good for that short hour I had to make a fuel map from scratch. If you want send it back and just pay for shipping $10 and I'll do it for free since you already paid for it before but never used it.

Not bad for the 1 hour. Stayed right on that 911 turbo's ass for a lil bit but we never had a chance to really get on it, especially with the full load.
Not enough for me. Remember my aggressive timing map I used on my car that I showed you? I need to do one for you like that when we get more time. Get me some race gas and I'll make that B timing switch really worthwhile.

Dyno #'s are just for tuning purposes IMO. The #'s spewed from one dyno to another have way too many variables. I guess you can get a good idea of what kind of power you are making.

hey i know we spoke the other night about this sam. good work so far. do you think you'll be able to iron out the idle portion so that it stays away from 12:1 ratios completely? i know you said something about using the AC at times or not revving it excessively at idle either. you think more tuning will cure all of that? or is this just something that closed loop is going to always fight back on?
still, good stuff, especially seeing that unichip told me not to even try when i asked

I think its going to be a closed loop issue only. I'd have to sit and mess with it a little longer more than the 5 mins I had. I got it to hold 13 or above when it was fighting for a little bit but I dialed it back b/c sometimes it kick into 16 at idle. No big deal and will save gas at idle, but b/c the AFR will be lean may throw a CEL once the PCM learns the fuel trims. Into boost worked out fine.
