Runs look pretty good to me. I'd change FF to 100, duty bias to 30 across the board, to speed up the WGDC adaption process.

So, it you don't think I have anything to worry about? I was looking over the logs with a friend and we thought the Ignition timing looked like the DME was retarding the timing pretty bad.

Also, it looks like in the the Third Gear Manual Sport + log the engine over boosted pretty good. Is that normal? Sorry, I am learning.

Attached is another log, but on Map 2. I got scared after looking at the logs yesterday and the timing.

I see the drop in timing around the 5k mark.

Still just 91 octane?

After setting & map changes, it does take a few WOT adaptation pulls for things to start to fall in line.


likely smooth the boost curve out with some duty bias tuning & the timing drops, in most users cases is due to lack of octane, or tired plugs. I'd assume based on your modifications the timing corrections are stemming from the 91 octane fuel.

Ok, so would you recommend going back to Map 5 and adjusting the duty bias and FF?
Yes, I am still only running the 91 octane. I plane to add some E85 at the next fill up. Planing on a E30 blend.

Also, can you please advise what I should expect to see in Ignition Timing numbers?
Should I be concerned with the Over boost that occurred?

My plugs aren't crazy old, but I plan to upgrade them to 1 step colder NGK's as soon as possible.

I think you can stick to map 1 or 2.

Manually lower your FF from 150, down to 70

I’d try adding a gallon of 85 to your current tank (assuming you aren’t on e) and relog map 2

Ok, made the changes recommended above and got a quick log. FYI, apparently my jb4 app was setup to combine the logs, so the first wot is in comfort mode and the second wot is Sport +.

Hi,

So for future only log in sport + with traction fully off.

Duty bias settings, those look really off- set those to default & relog in sport+

Thanks for the info. I will make sure to log in Sport + only.

As far as the Duty bias is concerned. In the post above, Terry has suggested to change Duty bias to 30 across the board. Was that incorrect or was that only for Map 5?

Thanks

30 works, but I think i saw some values like 29 or something in there.

At any rate, double check them, ensure all at 30 & relog

overboosting a bit on tip in & timing doesn't look that great, drops across multiple cylinders.

How sure are you that your mix is e30? Did you measure the content at the pump?

Well, it looks like we will have to try the review again in a few days. I just downloaded a new, more detailed E85 calculator and it looks like I am only running around E15 at the moment.

Okay, thatís not necessarily a bad thing, as that now tells me why timing didnít look great.

Letís get your content up to e25-30 range & see if that timing cleans up

Ok, attached is an updated log with E-85. I should now be close to a E30 blend. I can definitely see on the logs that my IAT’s are really creeping up. Looks like the FMIC is moving up the priority list. Well atleast we have a cool front coming in next week, temps are supposed to drop from the 90’s to low 70’s.

This looks overall decent

Cyl 5 lags a bit, but that is usually always a noisy cyl.

How does the car feel?

The car feels good and strong. Honestly, I'm not sure what to expect though. My last car build was a LS swapped 240sx which had I completely different feel to the power band.

Currently, I plan to upgrade to a FMIC, but I'm not sure if there is anything else I should be considering as a priority.

I am assuming a very linear/ flat powerband on the LS swapped 240?

I'd for sure upgrade the FMIC, as the IAT's creeping up isn't helping timing.
