Brad - now that you mention it, if someone has a dyno run with AFR graph of a S2 so I could see what the stock fueling is at high rpm... I could add my CO+WOT and 'WOTPot' code to a (stock fuel pressure) 16V LH chip. I can't tune a 16V EZF chip remotely except maybe to add a couple degrees of overall timing, but I could make it more responsive with my code... hmmm.

New TPS didn't change the resistance I needed for my '86.5 which is good. Better, it took away some noise/intermittent weirdness.
I tried expanding the range since there was less noise, but it was too much fuel. (It will take more complicated math to do it if necessary.)
High 14's at WOT. 390 became 0 ohms at the LH plug. At the test port, there was no continuity between 'B' (WOT) and 'C' (ground) with the throttle full open.

After a lot more testing of different exhaust combinations, it appears to be more of a problem with automatics (different gear ratios?). I have made two versions of the LH chip for autos and manuals which should cover basic exhaust changes. MAFs vary in output at WOT, so a WOTpot is still recommended for X-pipe/dual exhaust(/RMB).
With two LH versions, I was able to make the 5-speed version more like a GT, with a 775 idle, and the 6700 rev limit. The auto now has a 700 idle/6550 rev limit.
For those with stock chipsets that feel especially masochistic, I've added a WOTpot enabled stock LHx721 image (16V soon) and TunerPro definitions for DIY madness.

Just installed Porken's latest version (S300 v3.5) EZ & LH performance chips (86.5 - S3, Manual, Cats, RMB, LSD). MAN! what a difference!!! You can feel the extra torque in the seat of your pants and the snap of your neck... all the way to redline (increased to 6700 rpm)... doesnt let up, just pulls and pulls and pulls and... well, I eventually had to let up cause I ran out of road but the Lambo, 911 and a few other exotics I was running with couldnt believe how the "ole girl" could keep up!!! Well done Ken!!

What effect, if any, will occur if black cover is not replaced over eprom on LH comp?
I installed PORKENS latest chips but still need to replace FPR for full impact.

Stock chips....okay, Porkens one chip........nice, Porkens two chips and '87 high presure fuel regulator......WOW!!
Can't imagine what it would feel like going back to stock chips
