Thread: What ECU is this from ? calum need ur help!!

im saying that its from a sr20ve but other people r saying tis not cause it rev to 8000 rpm ... tell me what u guys think ... thanks
numbers were scratched off ... the important ones lol
but these werent

Look closely at the ECU label shown in the 1st picture. Post here all numbers below 4H.

The one you are most interested in is the one saying 23710-#####.

Looks identical inside to my sr16ve ecu. Id be suprised if 20ve ones look the same inside... they might though. Never seen one myself.

^^^^ Yes.

yeah its says 23710-###00 the last 2 numbers appear to be 00 .... its obvious that part of the label was scratched off under that 23710-###00 there is another number a18-g54 bj then the rest is scratched off ... i also noticed that in the center of the mother board theres a19-001 bj7 then in a square box the number 3 is in the middle right next to that series of numbers

this ****in blows it could still either be a sr20 ecu or a sr16 ecu ...the numbers i need r missing ... im getting tired of trying to figure out what i purchased ... i guess my question is if calum could program my ecu or would i have to to go out and get a stock b 14 engine harness and ecu ... i hope he can cause im running out of patients with this **** ... thanks for all ur help guys

OK, wild guess here... it IS from an 1st generation SR16VE!!

Since the # ends in "00" we know it si not from a N1 or later. The 8000 rpm limiter without a doughterboard is a 1600-giveaway also. No SR20VE was programmed with this limiter.

Finally....

The 23710-2N500 were marked "4H" like yours.
The 23710-5J000 from the SR20VE were marked "4G".

Also look below the missing numbers on the top label. There is anothere last row of numbers.

If it looks anything like A18-G54-BJ7 ... it IS from an SR16VE!
If it looks more like A18-G60-C85 ... it IS from an SR20VE.

This is of course a wild shot here but... sorry, those are the ones I have in front of me!!!

...but I wouldn't use it on your car. If your swapping into a B14 SE-R its much simpler just to use the stock wiring harness and reprogram the B14 ecu.
