Rich Idle, Lean Cruise?

[RunawayValet]

Basically it idles around 10.5 afr and at lowest throttle while still moving it runs about 13, any more throttle it goes straight lean. I just recently changed to e85 from cam2. The car was running pretty decent with the race gas. The only values I have altered in ecuflash are injector latency and scaling. At first I tried only switching scaling from 1002 to 700. I have since tried several scalings from 750-560 and multiple latency tables including 2 different sets directly from DW, all changes affect it minimally.

Car is a 92 TT tuning with chrome and ecuflash. AEM uego with brand new sensor plugged into front DP about 16 inches from turbo. No exhaust leaks. Running a walbro 400 for e85 and DW 1000cc injectors and dr650s. Otherwise a pretty stock car. I am running 45psi fuel pressure through an aeromotive fpr, pressure jumps to about 55 when you give it throttle (is this enough?). I have checked for vacuum leaks a thousand times I cannot find any.

The MAF I'm pretty sure is stock although I do not know for sure because I do not know what numbers it should have and there is a K/N sticker and cone filter on it.

I am sure it's something dumb but I am lost lol.

make sure your latency numbers are correct. They can have a rather large impact on the variation of idle to cruise.

[RunawayValet]

Well I have tried a bunch. I'm debating on changing them around individually... I will try, but I feel like there is another issue.

[RunawayValet]

Well I changed latencies and scaling around a bit, and added some fuel pressure. The AFRs are better but it pukes and stutters like crazy under a load... Which it did not do before.

[anyonebutme]

how did DW send you 2 different sets of latency for your injectors?

[RunawayValet]

They didnt, I got them online. I cant find the ones they sent me. I realize they are specific but they aren't THAT far off. It got to the point where it was straight rich at idle and flat line under throttle. I did have to replace the wideband sensor I wonder if the o2 sensors went bad too.

[RunawayValet]

So I switched my wideband to the rear bank and it pegs 10/1 constant occasionally going to 11 under WOT. Why would one bank be lean and the other be rich? My fuel lines are completely replaced and I even switched the feed and return sides..

[anyonebutme]

what are your trims. reversed trims are a sign of reversed narrowband inputs

[RunawayValet]

Reversed inputs? as in like I plugged them in wrong? I didn't think that was possible for them to reach..

So I changed plugs because I thought the Leaded fuel may have ruined them like it ruined my wideband sensor. But it did not help.

I ran a log. Most of the time STFTs are 12.5 and -15 respectively. LTFT lows are right around 0 each. It idles good, LTFT mids are 12.3 and -12.5.
I also tried unplugging the o2 sensors, reflashing and driving but it didn't seem to help at all.

Under ANY load it breaks up and pukes and stutters. After it breaks up a bunch it takes a few revs to get it to sound decent again. Almost as if it ran super rich and needs time to clean the plugs off. I wouldn't think it was spark blowout because the plugs and wires are new, and I gapped these plugs even tighter. I switched coil packs too. The wide band also does not match the LTFTs I am getting.

[anyonebutme]

You're harness needs the pins for narrowbands swapped, contact whoever you bought the setup from and they will get you squared away.

[RunawayValet]

I switched them it runs worse. It actually makes the rear trim decent but thw front is like -25. I cant even really accelerate it just breaks up so bad.

[anyonebutme]

trims should only go to +- 12.5. what did adam or brett say?

[RunawayValet]

Adam said the different emissions spec cars were switched. Even thoughbi am pretty sure it is fed spec. He had me switch it in the flash program but it only made it worse. I need to call adam today and ask about-25... question do the o2 sensors do ANYTHING when your at WOT?

[anyonebutme]

While the O2 sensors arn't used at WOT, your trims are.

[RunawayValet]

UPDATE So I actually bought a new o2 sensor, and while removing the old one I found that the wires had touched the manifold and melted three of them together. I fixed the wiring. Now I am getting decent trims. Lows are ~2 AND ~1 AND mids are around 3 and -3. However according to the wideband I am still running pig rich on the rear bank and about 4 points leaner on the front. Even worse is that I am still getting this terrible breakup around 5k RPM, at any boost it breaks up around 5k unless I am sitting idling.

Plugs are gapped at ~28 and are NGK bkr7e remember this is e85. Its hard to tell which bank is correct... the lean front or rich rear.
