Turbo Installed - Post Test Drive Questions/Problems
 

My turbo is installed along with the MAF delete, IAT install, 550cc injectors, FM duel feed rail and LC1 WB. I free air calibrated the WB as well. I had installed the 550's before the install and scaled them. I am running 10e HR code.

WB is showing I am running pretty rich at idle at about 11-12:1. I run pretty rich across the board at all rpm so far too. When I get into boost I spool to about 4000-4500rpm and/or about 7psi and then the car just falls on its face hard almost like a fuel cut. I am imagining it is just an over fueling issue right now. Any help? I dont mind running it really rich so I can get through all the gears and full boost and then scale it back rather than run it lean. I havent even really touched the fuel tables to tune yet because I cant really stay in boost and since I have been running so rich.

It also sometimes takes a couple tries for it to start now. Again, I think its a fuel issue. It starts and runs fine when it catches though. Revs smoothly throughout with no load. There is definitely some over run fuel being burnt as well.

also every time I open Megatune now it asks me to send and burn to controller even though i keep unplugging the ignitor and saying yes. do i need to keep unplugging it? Why I am getting prompted over and over?

Air/Fuel gauge on Megatune obviously doesnt read anymore, and Lamda gauge is in volts, is there a WB A/F gauge I am missing?

Fuel settings:
Accel TPS
Rate - Value
8.0 - 2.7
5.1 - 2.2
2.9 - 1.4
1.0 - 0.8

Cranking Settings:
4.3, 4.1, 3.9, 3.7, 4.0, 3.7, 3.2, 2.6, 2.1, 1.9

Req Fuel 5.9

Thanks guys. This is a PnP too.

overboost settings.


are far as being too rich....tune the fuel table.

I don't FWIW. I don't think you need to unplug the ignitor unless you are doing firmware upgrades. Do whatever you feel comfortable with since it's your car.


I think your accel enrichments look way too rich.

You guys I am sure know WAY more about this then me. What do you think my accel enrichments should be backed down to?

Any advice on the cranking issue? It will crank and crank for the first turn. Then it will crank and start for the second.
