Unfortunately I got word on the way up there that track conditions weren't good with 1 car sliding into the wall at the start of the track already so I decided to reschedule. Hopefully next weekend.

Good call. I hit the strip yesterday and they were only running one lane due to poor track conditions. My best 60 foot was 2.4, should have stayed home.

So I finally got a chance to get the car to the track, but it is definitely going to take some tweaking to get this working better. Overall best run today was 10.91 @ 128 with extreme throttle closures throughout the entire run (log attached).

First thing is the stall. The current stall in the torque converter is really high and feels loose pretty much all the way to redline and barely drops when shifting. I've spoken with Andy about this and I'll be pulling the torque converter this week to send to him to adjust.

Second thing is the TCM. The EZ TCU was pretty simple to setup/install, but lacks more advanced customization directly through the TCM itself. Basically the torque converter clutch never "locks" when at 100% throttle (no option to set that up through the unit either). There is an extra wire which can be driven to ground to manually override the lockup so I'll be talking to Terry to see if I can control this via the JB4 somehow, but it would be nice to have some options directly through the handheld interface. The other problem this amplifies is overheating. Since the TC never locks up, it generates A LOT of heat throughout the run. I have a more than sufficient trans cooler and still was getting overheating warnings after basically every run. This TCU also lacks any form of true logging so I may end up looking for other options.

Third thing is gear readout. Since the car has to stay coded as a manual and use the "manual" way of calculating gear (basically a formula using road speed, rpm, final ratio, etc), the DME and JB4 have no clue what gear the car is actually in (since all the slip in the torque converter can have the car at the same speed and the same rpm in virtually every gear). This creates issues for things like boost by gear. I've worked out the serial protocol for the EZ TCU and can read the gear parameter so I may end up making a little chip to feed that into the JB4.

As far as the throttle closures, I really need to get my rpm limiter out of the way and just shift it a tad earlier to see if that will clean it up.

Anyway, I feel like once I get these 3 things worked out the car will be incredible. I'll keep this updated as things progress.

Should be easy 9s@140 once sorted. IMHO the biggest problem for performance was the converter slippage causing you to do half the run over your rev limiter with 80% throttle closure. On the DME not reading road-speed properly we'll have to figure out what changed there as it read fine with the MT. I think that speed sensor is in the right rear hub? It feeds a frequency signal in to the DME on spot #17 on the gray subconnector IIRC and then the JB4 reads that from the DME via CANbus.
