Is the fuel trim supposed to max out like this? Anybody notice anything else here? Not sure if this is because of my mods or not. I went a different route then most on intakes. I'm using AFE Powers closed air intake system with snorkels. Homemade Ram Air setup with stock active exhaust.

It would be better to post the csv rather than the graph.
But yes, the trims look pretty high. Anything else you running (E30, etc)?

23 GT2 - Running 3.5 gallons of E85 per tank.

A log of you driving around doesn’t help. Set your JB4 to start logging at 80% throttle. Do a WOT run from 3rd into 5th then post.

ok, totally new to this, I will look into getting that set and repost. It was at 70%, now 80%.

So here is a different log 40mph-90mph. Same fuel mix above, 3.5 gal E85 added

Assuming your tank was empty (or you only had pump gas no more than 10% to start with), 3.5 gal E85 to fill it up sounds about right. Hard to tell for sure since E85 content and ethanol content in the gas isn't known for certain.
If you are going to continue using this route, I suggest getting the Fuel-It flex fuel kit.
Your trims seem a bit high. One thing to try is disconnecting the battery for 15 min or so so all the learned maps in the ECU clear out.
You have very few timing corrections, so that is good. If you can get the trims down, I would try map 4, that would be a kick in the pants. Just check the values in ign2 through ign6, these are the timing corrections. 0 is ideal, occasional below 3 or so is still OK, consistently higher under boost and you need to back down to a lower map. That's what I was using until I switched to WMI.

Thanks for the response. I should of stated I run 93 pump gas and this was the first time adding it the E85 to it. So I just put the E85 in and then topped it off with 93. I do realize I need to run it down to empty before doing it again. Yes the fuel kit will be added at some point. Trying it out first. After reading this I think resetting the ECU is a good idea with running E85 to get rid of the old maps. With trims being that high and the throttle closing I was concerned about that because I heard that pisses the car off and cause limp mode fter too many times, but I'm new to this and not sure I'm looking at it right. I went into limp mode after adding the intake setup a lot, and even before that. I mainly got the JB4 with the EWG wires to stop that.

datazap.me | tshing02 | First Run Map 4 E30 Blend

Map 4 run. EWG wires on, FF =50 Default Wastegate Pos = 60 Reset ECU, Impressive feel. How's it look. Found a good logging viewer. At least for me it is way easier to read.

When your changing fuels like rpoffen says it’s a good idea to reset the ecu by disconnecting the negative terminal of the battery for a few minutes. 3-5 is plenty 15 is over kill. Log looks good. Cheers,

after resetting it, I dove it around a bit, let the ECU learn, Seems it all straightened out. Very Happy with it now.

Pretty soon, you will probably want more, I did.
Went to WMI and dropped another 0.4 seconds off my ET.

Looking to go with a TCU Tune next, probably Lozic. Terry said I have a bad connection on one of my fuel wires. Using the plug and play adaptors with posi-taps. Guess I got a bad tap. Going to change them out. Not a fan of posi-taps.

Yeah, not a fan either of those taps. I carefully cut the wire and soldered the tap wire on, then covered it with heat shrink tubing.

Plug and play sensor and be done with it.

Not sure what you are referring to. A sensor, could you elaborate on that? I do have the plug and play adaptors installed with a pos-taps on the red wire.

 

[ChaneRZ]

This is what I have. Mine is not posi tapped. Has a quick release. Well it doesn’t matter now because I have ecu tune and don’t need fuel wires.

I used the PnP wires, but you still have to tap them yourself, all it is when you get it is an extender basically, gotta tap it yourself. I didn't use the posi-taps, I soldered the correct wire directly.

yeah that is the correct way, think I will do the same. eliminate that connection there altogether. How do you like your Lozic ecu tune? I was thinking -10% but I see you are at -8%.

Guess I have a different style. Those are cool.
