As for the RIP in my sig... That has been there a looong time. My '04 G got wrecked 2 years ago and was immediately replaced with the '06 I currently have.

I could say....
The Motec is as reliable in the racing platform as the OEM ECU is in the stock setup.

Hey, everyone..why dont we get back on topic and instead of arguing which EMS you think sucks, why dont you talk about which EMS you like and why(using personal experience as a ground point) Most of you guys are arguing about **** you don't even have no have personal experience on...and then your arguing about arguing about which ems's suck...lets try to come back to topic here and possible(doubtful)turn this into a useful thread instead of a pissing contest.

The TC issue was discovered by Jason a long time ago, but SGP wasn't very forthcoming with a replacement until Jason called them for me. They thought it was fine and we thought we could work around it. Now it seems that the TC in my tranny is possibly still stock (even though it should not be).

, damm... that sucks...at least it seems like you got that taken care of

I'm not seeing even half of the capability listed on Edelbrocks site...or in their software. Never mind the fact that Edelebrock is one of the most successful aftermarket performance companies in the world, and could probably outright purchase motec, yet they chose to go with the same electronics as ProEFI did! Seems like someone at ProEFI made a pretty wise choice if that's the case.

I know you were poking at the system, but in reality, yes it did find the problems, throw a CEL, shut off the boost, shut down the throttle, and limit the revs. It put me into a limp mode and a boost cut mode (not sure of the name) and when we got it to Jason, he was able to see that an injector was bad.

Do you have transmission temp being logged or displayed? I would be very interested to know what kind of temps you run after a few runs.
I currently have the GTM-5AT and it is very high stall at 14 psi of boost (just under 5k rpms). It launches like crazy but the amount of heat generated is just unreal, even with a tranny cooler. It is probably perfect for drag racing, but not too good for road racing or the mountains (at ZdayZ, I had to keep the trans locked in 4th to keep temps below 240 degF
). I had Andre at Edge build me another one from an '06 with heat control in mind (more efficient, only slightly higher stall, higher STR).What issue were you experiencing with your (possibly stock) TC? I was actually considering throwing a stock TC back in for comparison but decided it was safer to have Andre strengthen the internals at least. He wouldn't let me keep the stock stall either (he said I would be unhappy with it)... By the way, although the FSM states the stock stall is 2600-2900 rpms, he said that is in no way accurate and only possible with "cavitation", which he eliminates when he upgrades the TC. I didn't exactly understand what he was saying, but there you have it. Maybe some of this info is helpful as you rebuild your TC.
PS. No one else seems to run a 5AT temp gauge. The trans has 2 built in temp sensors, but I don't know of any solution that can read those over CAN. I've been bugging UpRev and Haltech to try to read those through CAN, but neither can at the moment. They figured out CAN for ECM stuff, so I don't know why decipering the TCM is so difficult. Can the ProEFI intrinsically decode all Nissan CAN channels or does Jason have to figure it out one by one? To make it worse, I'm afraid the CAN packets are likely different for different TCM versions across different models...

The point of his post is that the testing and adherence to manufacturing guidelines when it is put into literally 1,000,000's of vehicles are much more stringent that what other aftermarket ECU's go through.

My point stays the same......The track record is not there as yet...I am sure it will get there....but its still in a infant stage. I am ONLY speaking for myself here....and once again....I am not trying to deny the potential of the ProEFI. At one time...I felt the same about the Motec
Firm example:::::: The iPhone! No one can deny its greatness. But I refuse to buy one until it had a track record and was proven....

If you are, then you simply do not understand what the OEM's DEMAND of their suppliers. Their failure rates are listed in the parts per MILLION. This sheet was included in my ProEFI. Post which one (if any of these tests the Motec would pass).

Let us wait until ProEFI fix all the bugs or have all the feature working before we all kiss their ****... Utec promised us so many things but look were they are now? Only time will tell so stop the nuthugging!! ProEFI does have so many promising feature a head of them and I myself is interested on what kind of EMS they will be once all the features are working.
Well said
Correct .....I am speaking about the EMS as a whole...You have made my point....the Motec has already been proven... Thanks.
Believe me.....I am watching the ProEFI very closely......so if this thing turns out to be more reliable than the V-Pro, I will install it.
