JB4 Map 3 log check

[Overa25]

Hard to say. Could be bad gas. Have you done a ecu reset where you disconnect the battery and reconnect after about 5 min

Not yet I’ll try that when the sun goes down so temps aren’t as bad. It’s 112 where I am.

 

[Overa25]

Not an expert, but learning as I go. I think your timing deviations are too high. I would suggest Map 2 based on your octane level. IAT's were high for sure, but I don't think that would pull timing. Maybe a bit more e85 would help with octane, but if you can't accurately measure the blend, it may be tough to dial it in. As others have said, gas marketed as E85 may be more like E60, etc., so even with 5 gallons you may not be at E30 overall. Hopefully a couple other folks will take a peak at the log and have some advice.

Im gonna try a reset first then do some logs on map 3 again. If it’s the same Im gonna do some logs on map 2. If those are good maybe I’ll have to stay there. But after that I’m gonna try another gallon of e85 and see how she logs.

Even at E70 which is winter blend 5 gallons is plenty. I run 4 gallons of E70 and have no timing issues when pushing 22-23 lbs of boost. I would unplug the negative battery terminal and wait 5 min and plug back in and give it a day and re log. Careful if you get to much e your going to have fuel crashes

Yah let’s see your map3 run with ecu reset. If it’s still pulling timing, then you really have a bad gas.

Should I keep it on map 3 after I reset it on change maps

 

[Jaybone]

Yes keep map 3

How does this log look

How does this log look

Looks ok it’s common to see a bunch of .08 in corrections after a battery disconnect. I would re log in a day or two after you have some miles for the ecu to learn the fuel and then will reevaluate

Sounds good. Thanks for the help man.

How does this log look

.8 all the way across is normal after an ECU reset. Cylinder 1 is measured differently than the other cylinders. As long as 2-6 are all even and .8 that is typically fine. Try a longer pull through several gears if you can.

 

[Travis Wills]

Can you take a look at my logs. First time running ethanol on map 3. Filled up about 10 minutes before I did the log. Thanks

Try a reset and do longer pulls. You were pulling a lot of timing there but you should always do a reset when you completely change your fuel.

 

[Travis Wills]

Sorry to bother you again. Took this log 40 to 80 on map 3. I installed the ewg wires right before. Hopefully it’s just the heat. The ethanol mix says e19. I know that’s estimated but can that be the problem?

Still doesn't look good. Do an ECU reset and test again through several gears if you safely can. Don't put 5 gallons of E85 in a Stinger tank. That will put you WAY over E30. I put 3.6 gallons in and got E28 from my Fuel-IT sensor. Start small and move up as you go. There is such a thing as too much Ethanol. You really want just enough Ethanol to prevent knocking. Remember E85 has much less inherent energy than Gasohol.

Ok hopefully everything looks good now. And if so can I run map 4?

Log looks very very good. Be wary map 4 has very high octane requirements. So I would do one nice long wot pull and check the log.

 

[StingertimeNC]

Damn, no Timing issues at all! good stuff. Maybe Travis knows what he's talking about with that ECU reset!

Like Jaybone said, log it. Send it to Terry at Burger for a check. If he says it's good, then it's good.

 

[Overa25]

So here is a log on map 4. How do I send it to terry?

I can tell you it looks good. Just keep an eye since getting up there without either cpi or wmi can push it. But the log looks good

CPI?

 

[Jaybone]

CPI?

charge pipe injection

 

[Overa25]

charge pipe injection

Is that extra injectors going into the charge pipe or throttle Body.
