twin turbo installed looking for a little tuning help

[riversedgeservices]

I've got the car running really well but still having tip in KR , the boost builds fast and I get KR then it goes away, if I roll into it slower it doesnt show any knock or very slight , whats the best way to take care of this.
Just installed my msd BAP this morning to handle the fuel pressure dropping off

I have only MAF tuned it , also when I tried to do VE tuning the car would only fire up and idle rough for a bit then stall , (I'm thinking my VE is just way to far out ) any insight on this would be great also.

As it is the cars is insane right now and fun but want to be perfectly safe on KR

My build
416 forged 9.8 comp
102mm throttle body
fast 102 intake
lingenfelter gt14 cam
ported heads
agp twin turbos 57/61
10-12 psi springs gfb boost controller set at 0 duty cycle for now

Thanks in advance19wot.hpl

You'd need a 2 or 3 bar MAP if you want to tune for boost.

What MAP are you currently running anyway? The MAP kpa does the opposite of what it should be doing, you go WOT and it actually goes down to 70kpa instead of maxing out at 125-130 if you were using the 1 bar sensor.

Looks like you may be out of fuel injector or your pump can't keep up, estimated fuel pressure is dropping under WOT. I'd be checking that for sure.

Also with a setup like your you need to disable Desoot mode to prevent lean spikes when you mash the throttle and disabling burst knock should be done as well.

I am running the supplied 3 bar map that came with my kit but not sure what to change in the tune for it to read correct (i'm a nubie lol)
I have just installed my BAP and havent done another WOT pull yet to see if it will keep up , I have the zl1 fuel pump installed , the vehicle started as a 2010 rs ss NA and since I have now boosted with my new engine.
I will disable Desoot and burst knock and retry.

You still have Burst Knock enabled - that might be pulling some timing when stabbing the throttle.

What fuel system you running, because your fuel pressure is tanking big time. Starving (going lean) can kill your motor quickly.

zl1 pump and just added my BAP today and am going to retry a wot run

Do you know exactly what MAP sensor it is?

Did it come with a part number or any other information.

Running the tune with the wrong MAP sensor info can cause some harm too, as it doesn't know what is really going on.

If the sensor is a ZR1 or ZL1/CTS-V MAP sensor you'll have to change the linear and offset settings to match that.

[dreksnot]

This is what I have setup for my 3bar MAP that came with the AGP kit.

MAP Sensor Linear: 312.50 kPa
MAP Sensor Offset: -11.25 kPa

This is what you have:

MAP Sensor Linear: 128.13 kPa
MAP Sensor Offset: -0.31 kPa

I'd say - STOP! Fix the tables and stay away from WOT pulls until you have your fueling and airflow dialed in. After changing the MAP settings you're going to have to fix your MAF table. That's what I'm saying.

^^^^^ Listen to the man Don't just jump in without correctly tuning and start doing wot pulls - bad things will happen...

you need to tune VVE for sure for such a setup

[SultanHassanMasTuning]

you need to tune VVE for sure for such a setup, what injectors you have in there?

[riversedgeservices]

I tuned ve last night , runs way better , now just to fix the tip in lean knock I think.
Injectors are id 1000's

please use attached, your injector data was off

[riversedgeservices]

I will give this a try today , Thanks

[riversedgeservices]

Since I have a 3 bar map sensor now and am going to run boost etc , should I upgrade to the 2bar OS also for better boost tuning?
