Default Log review please - 09-09-2020, 01:27 PM

My car is kicking me to map 4 in the middle of a pull. Last cause is always boost over target but in the logs it is never going 1 psi over target. I have raised the limit to 20psi but it is still happening. Could someone take a look at this log and give advise please. Thanks in advance. Car is e92 manual Rwd:
jb4 on map 1
Aluminum intakes(end where coolant bottle was)
Mhd usa pump gas bef
Charge pipe w/ Tial bov
Cdp's
Stock turbos
93 octane, stg 2 lpfp

Couple of things...

Timing doesn’t look great, id assume lack of octane

Bump your FOL up a bit as well, try 60

Thanks Dave I went through my settings and found that the settings were set to 4/3 not 4/2 for bef. This lowered the boost target back to 15 psi. I tried putting the fol up to 60 and logged it. The timing looked worse to me than when the bef setting was wrong so I put fol back to 0 and logged it again. I'm attaching both logs. Can you take a look at them and let me know what you think. It's running very lean to 3000 rpms and timing doesnt seem good even on only 15psi. Thoughts on this? Thanks, Vince

Timing doesn't look great on either tbh.

I am going to assume the AFR being lean, coincides with the car trying to acheive target, as it comes back down after.

Do you have access to any better gas? or even e85

E85 is a little hard to get here but it can be done. Was thinking about trying it starting at 30% and going up from there. To get full benefit when I get up to 40% I have read I should put the e85 bef in it. Would it be possible to run it on 93 with the e85 flash if I cant get to e85 on a particular week? The last thing I want to do is to have to constantly flash it if I cant get e85. Thanks, Vince

We'd need some logs, but you can run e30/40 with the pump flash.

Dave, I put e85 in the car. Mixed it with 93 octane to 35% using an e85 calculator. Made 3 pulls in 3rd gear, traction control off from around 2000-2500 to 6500 rpms. Individual timing seems to have smoothed out between cylinders but the avg ign went from 3.3 up to 4.1 by the third pull. any ideas on why this might be happening? This thing ran so much better when the jb4 was mistakenly set to 4/3 on the tach. Granted it was making 18 psi but the avg ignition wasnt any worse and that was on straight 93 octane. Thanks for all the help. Attached is the third pull.

Hey,

This doesn’t look bad

It felt faster because you were at 18 psi, this is more 14-15.

Ave_ign is trending down, that should keep going down.

FOL- bump that to 70 or 80

Relog & we can likely jump up a bit

Ok good. I will bump the fol up and relog. How long does it take for the avg ignition to correct? Is this something will take 20 or 30 hard pulls? Is there any prerequisites that need to be met to get that to correct? Example...does it have to be during the long 3rd gear runs or will it correct just driving semi civilized my options are limited as to where I can make a 30 to 95mph run.

I bumped fol to 80 and made a pull. Trims were still up near 50 so I bumped it to 90. This is a 2000 to 6000 pull. It seems the avg ignition is dropping a tenth or 2 each time I make a hard pull on it. Where do you think I should go from here? Is there a better map to be in than 5. I really dont want to have to make 30 pulls to get it back were it was if I change the maps. As I understand it map 5 reverts back to 93 octane if switched. Would 6 and just using manual boost limits the same as 5 a better option? Thanks

Map 5 is auto adjusting and isn’t as consistent as some of the predefined maps.

You could try map 1 or 2

Dave, This log is on map 2. Looks like cyl 4 is having issues above 4800 and trims are pretty high. Let me know what you think.

Hi trims do look a bit high to me as well, nearly maxing.

Are you still on the pump flash? If yes, try switching to the race flash with the e40, lets see if that helps the trims & if timing can hold we should be $$$$

Ok, this was on e40 with race bef. Timing looks better than it was on pump flash and total timing was dropping lower than it ever has been. Its still maxing the trims in the lower rpms as boost comes up. What do you think?
I added a second log from later tonight. Avg. Ign is getting better with every hit. There is a few strange drops in hpf. On the second log it is accompanied by a partial throttle close but the first log it occurs right before the shift. Not sure what that's all about. The afr stays in check while this is happening. Any ideas on that?
