Re: Under boosting on new turbo
Say as you wish, but I assure you I am aware of what I am doing. Quoting you and only quoting you, "I would not go above load 2.3 (pump gas) on these engines before 3500rpm. At 3500rpm upwards it's fine." Maybe English isn't first language, but from my understanding when you say 3500rpm up...

Re: Under boosting on new turbo
I'll get logs with that next time I'm out, unfortunately can't go for a drive at this current time. However I do have 2 logs, one which was driving with 100% wastegate and the other which was only running spring pressure at 0% wastegate. For some reason the forums doesn't upload anything I attach so...

Under boosting on new turbo
I have recently installed a BNR S2 on my car but I'm having issues with boost control. Originally when installing and taking it for the first drive, I was seeing boost levels of 22-23psi+ (!!!), while wastegate pressure is only 1 BAR. Turns out one of the covers on the back of the turbo was partiall...

Re: Questioning Logic of Stock Tune
There is definitely someone who can explain this better than me but this is my understanding. Like you said load is basically how much torque the engine is producing. The reason the targeted load drops off above 5000rpm is due to the stock k04 not being able to reach higher loads (with the stock BCS...

Re: Fuel Trims during WOT
Interesting about the load, you mean I can increase up to 2.4-2.5 or more as long as torque doesn’t have any unnecessary jumps.

Re: Fuel Trims during WOT
Okay, I can give that a try. How much more ignition are we talking? When I was initially tuning and plotting the data onto Virtual Dyno it claimed I was loosing / not gaining any more power with the ignition changes, or maybe it was wrong. In terms of load, what do you think I can target and reach t...

Re: Fuel Trims during WOT
The log didn't send, I uploaded it to Google Drive instead.

Re: Fuel Trims during WOT
It has been a minute, but I have a log for you if you don't mind checking over it and seeing if there is anything that alarms you or any suggestions. I have the rev limit set at 6200rpm. The modifications on the vehicle are as follows: - Stock Engine, Turbo and Intercooler - E30 Mix (EU98 + E85) - A...

Re: Desired AFR
I had to tune a vehicle the other day that was just like this. Turns out the Desired AFR parameter isn't the most reliable. Simply all I did was you have to cross reference with your tune. When you got WOT (APP > 75%) then it will be using the Open Loop AFR Targets despite what the Desired AFR says....

Re: Fuel Trims during WOT
Fair enough, I'll let you know. Aside from fuel trims, with ignition timing how aggressive can you make it when coming into boost to help increase the spool rate and what is a general amount of ignition you can get across the board with the stock K04? My K04 seems to flow a good amount of air seeing...
