Sounds good, I’ll try other gas stations and different/longer logs. I’m always in sport when I log too. How often do you change your spark plugs? I’m around 18k on mine. I’m going to try other gas stations first to see if that improves the timing before swapping them out.
What kind of timing values do you see without vs. with WMI? On map 4/5 running E30 I tend to see 14.5-15.5, but not sure if that's normal/ideal.
the ing1 target is usually set the same in the tune, its the amount of timing reduction you see that matters. for example, without WMI, I would get between 6 to 9 degrees of timing retard (pull), with WMI, I get none to 0.8 degrees
That hurts my brain. This torque based ECU is already PITA to work on, can’t imagine more changes on top of that.
As mentioned by Adoom your IGN1 is fairly low. I would suspect the optimal octane level is not reached. You can use JB4 map6 to shave off some boost off. Update your firmware and set your 1500 rpm to zero(which means all the numbers in the box means boost reduction)and 3 till 4500 rpm and 2 for 5000 rpm. This should give your a fairly flat 17 psi boost curve. Of course, bit 0,5,6. Your current boost level needs E30 mix or WMI.
an e30 mix should 100% improve timing. I cant promise it will make it perfect, but it should def improve it. Also, can you upload the video you took to youtube as an unlisted video, then link it here?
I’ll try E30 next time I fill up. And here is the link
EWG controlling boost at part throttle. Pretty normal method to prevent too much boost at low rpm hence preventing LPSI. It sounds ugly and feels bad but saves your engine’s ass
3.5 gal of the E85 shouldn’t make your HPFP crash no matter what. You should probably go get a revision for 1.3 91tune with 13 HPFP. He does have a tune with HPFP at 13 and can take more E. Also his 91 1.3bar boost curve should be super easy to add boost with JB4 if when you’re running E30, or adding WMI/CPI in the future. It doesn’t seem like this platform can get rid of JB4 forever so stacking is probably the best solution. All 93 boost curves are pretty hard to play with JB4.
What would be the difference between the 13HPFP and 10HPFP? The tune right now is for 1.4bar 91octane. Would getting the BMS WMI kit now be an option also?
It always good to have meth, but your car should be able to handle E30 without meth no matter what. Meth can be a solution for your current crashing problem, but it’s not how it should be solved.
I had same problem with my lap 3 tune i used jb4 and reduced boost 1-3 lbs with map 6 through rpm range and fixed the fuel crash and helped with ignition timing.
log looks good
Yea it's low boost. I will get another remap.
You dont wanna go over 5900.
My TCU shift at 8% lower.
