I am having troubles eliminating a lean spike that follows a rapid boost rise with the oem turbo.

Does anyone have some good settings for accel dload?

I have my map points defined by load / rpm

It is my understanding that boost compensation is only used when you refernce tps/rpm

I tried a number of settings, map slopes, etc. But i cannot get dload to work as i was hoping.

Any insight or suggestions would be apreciated

 

in your fuel map you should put a large spike of fuel where your turbo spools

my map is boost comped and has almost twice as much fuel at spool than at 7k

 

^ are you using boost compensation or are you just placing extra fuel into your base fuel map?

 

more fuel.. mine also peaks at inital peak boost.. ~5000rpm... then falls off.

 

If you are running a stock fuel system (injectors/rail/lines) on the stock turbo having it spool up very quickly there are a few things you can do to help control this but you will never be able to eliminate it completely under some enviroments.

You have the same problem as several others do, the stock turbo will spool up so fast you can't ramp into fuel fast enough to keep up so start tuning your map load points a little more proactive and make good use of your throttle correction adjustment table. Also O2 Feedback (with correct feedback settings) will help you out as it will to fill in for your changes in driving habbits and enviroment.

Also keep in mind accel will only help you as you tip in your thottle for just a few hundreths of a second as it falls off so your fuel maping combo (fuel map/throttle inj correction and injector advance) is the best answer for your issues.
