Get an obd reader, record ignition timing, and just turn up the boost on the JB+ until the timing starts to suffer. You are not maxing fueling on gasoline only. Stay under E30 if you blend. JB4 makes this whole process easier for sure

It is in the first post :) Stock dp just update to v24 and FF at 30 to start

It just takes more effort to dial in. On a stock dp car you don't really have to touch duty bias much. AA DP is going to be way less changes than catless for example

Looks ok, timing could be better. I only see Map 2 and Map 0 logs. Try FF 45 on map 2

Will need a few revs. I'll shoot you a PM later with what to try. Your AFR is measured with o2 sensor :) so the 14.7 was null. Terry thinks your car ran lean, so check the plugs if you haven't yet.

Nah now I'm actually curious though. I sent the "case study" to Terry to see what he thinks. I wonder how JB4 factors fuel trims and AFR into its operation and if it affects the boost control or this is more on the dme side. That no O2 sensor log had no business looking as good as it did for a...

now that looks like a catless MT log lol. Try these on V24 firmware only

Check your plugs and send a log after

? I'm surprised the car doesn't limp mode tbh.... Do you think this would just run fueling in full open loop?

bro what? ? both are disconnected? I'm surprised the car works at all, are you sure? The pre-cat primary O2 sensor is 100% critical to car operation if true, I hope you know how dangerous that is for your car

I can tell you how much boost to add based on how the trims looks if it datalogs properly, so I'd need to see another log

I get 14-15 mpg in my 3.0 manual ? Only driven hard and running on E25 this post is dumb as hell lol, mod your 3.0 and you wont ever regret selling the 2.0

all fine, just remove whatever as needed for warranty work. this is at your own risk!

smoother + not slower is still better

after you install EWG post up a map 1 and map 2 log and we can go from there. stock dp cars start at default 50 for FF and duty bias

Looks great to me, and I would say go ahead and add more boost but the trims signal is not working correctly. maybe another log? glitched out or something Also go ahead and drop FF by 2. Clean up that throttle a little also is this an MT?? tuning is behaving more like an AT car but I see the...

@Hasan is right. I adjusted mine while it was on the car no problem. Just take the cover off and turn the dial while its hooked up, car off. You can try turning boost down from default to maybe 2-2.5 psi and see if the car is any quicker. sacrificing timing for boost kills power.

Let me put it this way, stock tune has timing corrections on 91 ? hot running engine with a baby turbo If you decrease the JB+, it would help.

The absolute COLDEST A91 MT burnout ???

boost looks a little all over the place, but I need the actual datazap link and the log to be public
