Map 2 w/ 91 Octane Log Check

[whitepanda]

I just installed my JB4 with the pre gapped HKS Plug. Thats the only mods i have right now. Please advise and guide me on what I should be mainly looking at. Thanks everybody!

Useless log. Firstly set your JB4 to start logging at 80% pedal. Second get into 3rd gear about 2000 rpm and floor it (WOT) hold it through 3rd and into 4th or 5th if you have the room, you’re going to get going pretty fast. Then post the log.

Dam my bad man… I am completely new to the whole thing so I dont know what I am doing. But I will do that now n log it

That’s why we are here to learn. 100% throttle to log.

 

[whitepanda]

Okay I did what you said heres a log hopefully its good enought

 

[ChaneRZ]

What octane are you running?

What octane are you running?

91 from Chevron

 

[ChaneRZ]

Got some timing corrections which are expected from crappy 91 anyway. If you have access to ethanol, try E30 mix and log again. Reset the ecu after that fill up.

 

[whitepanda]

Dam okay. Any guidance on how to mix E85 and 91? How do I reset ECU. I apologize as I am completely new to the whole car scene let alone tuning. Thank you and I appreciate it.

Again a shitty log! One more time. Start driving the car in 3rd gear at 2000 RPM push the gas pedal ALL THE WAY to the floor and hold it there until you get into 5th gear.
Regardless of the shitty log you are pulling to much timing under boost. Try finding better fuel like 93 octane or add 5 gallons of e85 to 10 gallons of 91.
To reset the ECU disconnect the battery (it’s in with the spare tire) for 5 minutes or so.

There is a reason Burger doesn't recommend running anything other than map 1 if all you can get is 91 octane.

 

[whitepanda]

I appreciate the guidance guys

Lots of timing corrections, to be expected on map2 with 91 octane. Use a dragy to determine if map1 or map2 is actually faster for your specific situation.

 

[Oryan]

With timing corrections like that you're better off on Map 1. You ideally want less than 2.3 and 3 or higher is a sign you need to either lower the boost or raise the octane. 5-6 degree pulls like that likely won't end well long term.

Does this mean that it would still be okay to run 91 on map 2 if it is actually faster?

what map is recommended for 99 octane fuel for 3.3?

I am currently running JB4 on map 3, Intakes are modded, denso plugs gapped at .22, intercooler, backbox delete on exhaust, I think I have it right just wondered if maybe map 1 or 2 would be better as I am running a 48mm DB killer in 60mm pipes (to remove drone until I find another solution) and am worried about exhaust back pressure
