Alright,
I've been out tuning my car with a friend the past couple days everything has been going really well for my first time tuning. However after upping the boost and messing with timing the other night I've been having a problem with stalling after doing a pull. I'm tuning with Hondata S300 and I have "lean protection" enabled. currently it's set at 12.5:1 above 13psi. The night we were out tuning everything worked perfect and the car was pulling REALLY hard. Had A/f set around 13:1 to about 5-7psi and from then on it stayed steady around 11.7- 12 all the way to my redline at 9200. Boost was set at 16psi on my GT35R.

The problem started the next day. When going up an on ramp I gaver in second and hit what I have to assume was lean protection before i reached my rev limit. This had happened before while we were adjusting the fuel tables and normally it would hit the cut and the engine would keep running...good to go. This time however the engine stalled and i had to cycle the key for it to run again.

I hooked up the laptop and did a datalog of a pull in third.. there was no lean cut.. and it didn't go lean. I reved the car just about to redline, but when i let off the gas and engaged the clutch the car stalled again just like before.

So my question for you people is how do I stop it from doing this? It seems to be doing it everytime I floor it now. Is there a setting Im missing or something?

Any input would be appreciated,

How much vacuum is your motor pulling at an idle ?
What air fuel ratios are you seeing at an idle ?
You are running stock gsr cams ?

 

Thanks for the reply. Car is pulling between 21.5 and 22" vacuum, a/f is normally between 14:1 and 15. Yes they are stock gsr cams. One thing I forgot to mention is that I'm also running an AEM water meth kit. Full meth comes on @ 14psi.

Thanks again.
