How's the tranny temp? I'd highly suggest a gauge on the hose going to the tranny cooler. A couple pulls and mine's pushing 240 degrees F and I have to cruise in 4th till it comes back down. This is with a high stall (4500 rpm) converter from GTM. I have a more efficient one (3200 rpm) sitting in a box awaiting install.

Great numbers and happy boosting!

Just wondering if the ProEFI can reduce timing during shifts like I've heard the stock ECU does (and the eManage ultimate does)?

HMMM...I don't know about the tranny temp. I have a tranny cooler from SGP, so will that eliminate that problem?

As far as the shifting, this is the first auto Z with the Pro-EFI, so we are still seeing how it does. It seems to be learning the shifts and adjusting for the quick rev-up though. The 1-2 shift is pretty seamless now and the other shifts have improved. I have still only driven the car a few days, so we'll see. According to Pro-EFI, the stock ECU controls the shifting and will therefore adjust for the timing.

I think he is talking about the ignition timing of the engine, not the timing of the shifts. The ProEFI can't know when the computer is going to shift to pull ignition timing, but the stock computer also cuts throttle, so there is still significant torque reduction. You also have a built trans, so it doesn't need as much torque reduction to keep it alive. Also no torque reduction = fastest possible acceleration.

It didn't eliminate it for me. Heat kills transmissions - I would think you would want to monitor it. Of all my temp gauges (air, coolant, oil, trans), the tranny temp always reads the highest after running for awhile. Depends how you run the car and the specs for your torque converter, which generates most of the heat.
This is the cooler I have and it sits right in front of the passenger side of the radiator in the path of airflow (behind the cross-brace): http://www.bmracing.com/s.nl/it.A/id...&category=6172

The stock computer reduces throttle during shifts? I did not know that - how do you know this? The eManage ultimate manual only talks about decreased engine timing during shifts. I will generate a log of TPS during a WOT run and take a look...

It is interesting that you say the ProEFI can't know when the computer is going to shift - I wonder how the eManage ultimate figured this out? It is something I've been bugging the Haltech folks about.

Just the 18's. They are putting down plenty of power, though!

E-manage piggy backs the signals.... it doesn't replace them all together. The ProEFI and Haltech do.

I haven't had any problems with the injectors. Should I be watching for a certain symptom or problem?

LOL! I'm assuming you saw it today?!?! I haven't even seen it yet. Does it look good with the 1" drop and spacers?

Yeah, I swung by the shop just as they were finishing up the height adjustment. Looks Baller!!! But, you are gonna need a camber kit, because you will eat through those 20" tires in like 5,000 miles. Car looks dope though!

Sweet! I'll ask Pete about a camber kit. I have no idea what they cost, though. I assume I'll get better traction with a camber kit as well.

These are to fix the rear. The fronts have adjustable upper camber plates, so you don't need anything to fix the front. Tyler should be able to get the alignment pretty straight on the lift, but ask Han about the Porsche place in Tempe that specializes in lowered cars; just to get it juuuuuussssttt right.

That's a good point. I know all the stock signals are available to the Haltech through the harness though. They haven't said it can't be done - lol - so I'm still hoping it's possible. There must be a CAN signal that's transmitted between the ECM (actually the gauge cluster I believe) and the TCM that could be intercepted...
