Hi all!

E20 blend, 2 new runs

Map 1 4th gear

Map 2 4th gear

https://datazap.me/u/arthurwick/map-2-4th-gear?log=0&data=1-4

Did the E20 improved things? Thanks

Timing looks great on both logs. You can turn it up more if you want, but personally i would try using slightly less E next tank and try to strech out how often you need to buy e85 cans.

Good to know!

Would going into map 6 and add 1 psi more boost to let’s say map 2 targets be a good way to test it? Or should I just go with map 4?

I don’t plan to run the car with Ethanol blend at all time. I’m trying to find out how much boost I can add safely with this e20-e25 blend for the occasional trip to the drag strip, car will probably run on map 1 99% on the time apart from that.

I want to give my friend’s Stingray C8 more of a hard time when we go drag racing. Right now I’m at 12 flat and he runs 11.6

So I got 2 MickeyThompson ET Sreet SS to help with 60’ times and the JB4 to add a few whp.

Also, why do I have 2 big throttle closures (3000 rpm WGDC = 36 and 5000 rpm WGDC = 45) on map 2. Do I have to make some WGDC adj to help with this?

Let him have it on Map 6 lol at FF 40 (save after switching maps). Shift around 6200 to beat him lol

Map’s saved in the JB4 🫡

But logs will have to wait until tomorrow, just saw that it’s raining like crazy right now!

Map 6!

Pulled really hard but I wonder what the verdict is? Any adjustments needed? Why such a huge throttle cut around 2800 RPM?

 

[Thatpartsguy]

Evening everyone,
I would like some input on this log if you would. Why are my timings so out of whack? I cant seem to get consistent runs, some days it feels good and others its all over the place. I'm just concerned about hurting the engine due to knock. Thank you guys!

your logs look great I'm jealous lol

Man I don’t have any merit, apart from buying E85-R to make ethanol blends to follow advice from the guys on this thread, all the merit is for them!

Can’t wait for map 6 feedback from @ColonelAdama, wonder if it needs fine tuning?

 

[ArthurWick]

Doesn't look like traction control kicking in. Might need to drop duty @3k rpm by 5

TC was completely off. 3K rpm WGDC is set at 25 in the log, dropping it to 20 might help with the throttle closure?

correct, drop duty 2500 and 3000 by 5 and try again. Not sure if the little closure at 4500 is duty related or you hit a bump. confirm with another log

duty5500 to 55 too. Try to get ecu_psi to be about 1-1.5 psi below dme_bt entire pull
