GT32 at 13 psi

[SeanC]

well here it is. my tune started out super rich and i got a whopping 243 WHP out of it. once i leaned out the upper end a little the whole thing smoothed out and gained 30 whp. whoever said a/f has little effect on HP and TQ is a little off. i think my "missing" 20 whp is from my ignition timing being so low. thanks to my non-logging bikirom i have no idea where in the map the runs were made. i will be going back in a couple weeks with v2 cams and a WORKING bikirom!!!

here are the two main charts i have:



here is a quick video i made: (excuse the roughness

What is your whole setup?

You will definitely see some gains from tuning ignition. AFR really doesn't make any significant changes past 11.5:1 You must have been pretty rich on that first run..

[SeanC]

yeah i was really rich.

gt32iap manifoldbikiromebay fmic650'stial gate3" DP and exhaustthats really all the important stuff.

you got any hints for my ignition map?

[nissanfanatic]

I'd look for around 19° around peak VE and maybe 20-21° past 6k...

Any way of getting knock feedback..??

[SeanC]

i have a spectrogram program i just need to find another stock knock sensor so i can wire it into my laptop.

[nissanfanatic]

cool..

Since you are on the dyno, you can also use the torque curve.. If you make a change and torque goes up, you just took a step in the right direction. If you change it and torque goes down, you just took a step in the wrong direction, go back to where you were.

Are you having any boost creep problems with the GT32 and IAP manifold?

[SeanC]

boost held dead even at 6, 8, and now 13 psi. and mine is recirculated into the DP and it intersects it at a 90*

[240 GTR]

is that an ams gt32?

[Florida240sx]

Nice, can't wait to see after the retune

[SeanC]

yes. i am excited for the cams!

[xTearsFallForeverx]

Nice stuff. Cant wait to see your full tune numbers. I think I'll be going with a t3/t04e 50trim. Just ordered my shortblock from AMS. Cant wait to get it!

[Brandon93240]

Thats pretty good numbers. I made 297 and 288 at 12 lbs with the Gt32 and crower 264's. I think I still have the printout somewhere, if I find it I'll post it.
