Who is running JSPEC ECU in ASPEC TII
I wanna who is running or has run a JSPEC ECU in their ASPEC TII. Did you have any problems or did it run fine. I'm preferebly looking for people with an ASPEC harness and not the JSPEC one. Did you even notice a difference in performance (hot topic)?? Some members might want to know if it is worth purchasing one or if problems will occur with this setup i.e. not running properly, too low octane in the states (common argument) etc...
Any info with your experiences will by much appreciated and will help out with discussions in the future or for some info for other members to search upon later on.
My experience with the JSPEC ECU has not been a good one and other members are having problems also. Just checking to see if it is the computer itself or if it is a problem with the pinouts and wireharness. Thanks in advance for your help!

Seems as though there is no difference between the N370 & N374 from past threads. There have been a couple of people that have had problems, but I'd say it was not because of the wrong ecu, it was a problem with that ecu or some sensor.

The differences between the ECU's are for the different ancillary equipment and functions, like the port air, EGR and AWS solenoid valves (not fitted to Japanese cars) or the speed limiter (not fitted to US cars).

BUT STILL the main reason for this thread is to see if anyone running the JSPEC ECU with the ASPEC harness and seeing if maybe there is something different on the pinouts or wiring. Trying to see if it is the ECU or if the two are even compatible. Basically trying to find out if it is just a problem that a few or all are having with swapping ECUs.

I'm doing the exact same thing your doing, i'm trying to find out the opposite. JSPEC ECU w/ ASPEC motor or harness.

right now, i'm running a N370. I tried to run the N3Y4 as i was told it is for a S5 Turbo. I have a Knight Sports FCD (connected to boost sensor) but no chips or upgrades for the N3Y4 ECU at all.
