I've been kinda thinking of doing the TT ECU for a while now. I know that I read it somewhere, and I'm sure that someone posted a link in here also. But I was thinking. Could I theoretically run a TT auto ECU and the TT auto tranny attached the GE, and have a running vehicle? Just curious.

yes you can, thats a good upgrade for automatics as well, the tt trans can take more power.
havent had time to get it fully running. i got the new tps setup, need to get it on the car and see if that was the last issue, apparently it didnt like my aftermarket nissan tps, had to get the beech q45 adapter to go back to stock tps.

I should have it running friday, It would have been working, but apprently the aristo ecu does not like a 3 bar map sensor without alot of messing around, I have 440cc injectors and a 2jz map sensor on the way, once those are on it should be all good, and ill tell everyone the best way to do it. I think both the vvti coils and the stock distributor can work also, but I havent tested them out yet. I will test out the vvti coils after its running on the gte coils.

Im not going back to a stock ecu, for me the stock ecu is a non turbo sc300 ecu.
I am using an Aristo ecu on my na-t which uses a map sensor and coil on plug ignition, which is all I am really looking for in an ecu on my setup.
And actually, its the aem that is the problem. the aem has difficulty picking up the variable reluctor pickups (cam/crank) properly in 30 degree weather.
It can hardly even do it properly in warm weather but it gets the job done at least.
They had such a problem on honda's that they had to release an aftermarket distributor with hall sensors to use as the cam/crank sensors that work much better.
the cold weather usually drops the battery voltage enough overnight as well, to where the aem wont even show sync on until jumping the car or charging the battery overnight. It has nothing to do with the tune, if it doesn't sync, it wont even fire up. even when I get sync the aem has starting parameters are worse than adjusting a caurberator. when started my car ran like a beast, I had the aem tuned so well it drove better than stock, but thats if I could get it to start.
If you live where it doesnt get below 40 degrees, you would never even know this.
Over here, basically every morning in the winter is much lower than that, and my car was a giant aem powered paperweight.
The stock ecu picks up the signals so well it can start the car on a half dead battery if you need it to.
If the aem wasnt worth so much I would have smashed the thing into a million pieces office space style.
I had 2 different reputable tuners look at the car, I myself can tune aem's and i am very familiar with the way the sensors are read as I am an electrically inclined person to say the least.
After paying several thousands of dollars (it is not cheap to get tuners to keep looking at your ecu), I decided what an incredible fail the whole thing was, and I am going to use an aristo ecu and use all that money on an vlsd or something.
And the idea is that its just a headache for me, and once I post how to do it, others can use the JDM ecu's with just adding a handfull of wires, that I will have spelled out in great detail. It doesn't bother me how much work something takes, what bothers me is doing a whole bunch of work and time and money and it still doesn't work right. Thanks but no thanks AEM, I will be taking a different path from here until they can learn to start an engine in freezing temeperatures properly.
