Let's look at the tuning again when it heats up for sure!

Hey terry I had started a thread on the stinger forum about some weird limp on my stinger at exactly 94mph on map 3 or high, had it happen on a run on map2, did it first pull, not second. Attached a log of map 3 as well. Let me know. 18 rwd, cai, 30-35 percent e85 in tank and plugs at .22.

Yes I see the problem, fuel pressure tanking!

Less boost and/or less E85.

Okay I will try putting more pump gas in to see if that helps, if not, does that mean I have to pretty much lower boost up top on any map above 3?

Not easily, no. But this thread has some basics. While not all of it applies to the Stinger most does.

Less boost and/or less E85 to keep fuel pressure from dropping below 8 (1200psi).

Are we able to raise the boost higher than the 0-75 if we are using 100% methanol instead of the 50/50, to add additional fuel? I would love to be at +10 or 11psi 😁 I've been running 70% meth for over 3 months now and at 75 on the wmi map. It just kinda feels blah now and I'm ready for more. My 2004 hyundai sonata 2.4l is making more hp than my stinger is. 😓 but seriously it is. And I'm very familiar with tuning for afr and knock from my experience with high boost 4 cylinder motors. The stinger is begging for more boost!

I'd have to see the JB4 log for any tuning advice, but the stock turbos stop making power around 18-19psi. So that is as high as you'd want to run it in my opinion.

Took a few runs last night in the chilly 45f temps we have around here lately.

Mods: JB4, BMS Intake, BMS Prototype Intercooler, 93 octane, stock rims/tires, stock exhaust system, no WMI, full weight, etc. JB4 set to spoof intake air temp up around 30 degrees.

I'm really pleased with the trap! Had boost set to -4psi in 1st which helped off the line but with 1WD on stock tires traction is always the enemy.

Hey guys,

Apologize if this is a dumb question but I'm pretty new to this. Was doing some logs during the drive home today, and my Ign 1 numbers look way off compared to others I've seen in this forum. They get pretty high and look like they bounce around a lot more. Logs are attached. Is this normal behavior? Car is stock except for Stillen intakes and using pump 93. Edit: and Densos gapped to .024”

Thanks,
Dan

We'd want to see a log of what was going on before you went in to low boost mode, if you leave the JB4 connected so it can auto-log runs and appends them to the same file (under the app settings) makes it easier to track down.

Dipping down during shifts is not a problem at all. If you start seeing ign1 gradually decrease (like going down a set of stairs) as your RPMs are climbing then you should be concerned.

Hi Terry

I enabled that logging function. I was thinking of downgrading from v8 to v7 firmware to see if I have the same issue. Will I lose any settings or will I have any issues completing this since there are enhanced functionality in the newer version . I am guessing that it should be ok but I thought I would ask .

No you can move between v7 and v8 without issue, but won't make a difference. Whatever problem you have you probably have on any firmware version.

I only started to get this issue when I went from v5 to v8. Only upgrades I have done in the last couple of weeks was BMS Intake and AP intercooler. I had no boost issues on v5 with these mods. Other mods are ***/catback exhaust/spark plugs. I do have fuel wires installed. Anything I could check ?

Exhaust mods can cause the car to "over boost" a few PSI over target at low throttle and trigger a false alarm low boost mode in some rare cases. Capture the issue coming up in a log and I can setup a JB4 setting to accomidate.

Should be OK on map3 with an E30 mix. Post a log if you want me to check it out though!

No we can't change the injection timing with it, so you'd need a back end flash map to add that in if you wanted.
