ecu ?'s

[Lroi]

ok so I bought this ecu off ebay last year for my redtop...the listing said "tuned ecu" has rev & speed cuts removed...cool it was the only s13 redtop ecu listed I needed one so I bought it, last night I take it over a friends who cant get his swapped sr running...he compares before he hooks it up and he says I might have s14 ecu...ive searched for pics but couldnt find any...mine has no 62 sticker and some of the #'s on it are different then his

can anyone tell me if i have a s13 or s14 ecu? or lead me to a site were I can run these #'s the pics suck..couldnt turn off flash

#'s on it 237IM 50FI0 AII-000 G9 G91k 1417

thanks for any input!!!!

wait im confused..your friend says he might have a s14 ecu? well what engine does he have? s13 blacktop, redtop, s14 sr..you cant have a s13 sr and have a s14 ecu..if he has a redtop then plug in that ecu and see if it plugs in..if it doesnt then you dont have a redtop ecu (62 or 63)

237IM 50FI0 is for RPS13 63 Jan91-Jan 94 SR20DET AT+PS13

no...he was thinking I might have a s14 ecu, we both have redtops...my ecu plugged right in but still no start

thanks!!! we just found out he has other "issuses" at hand, think its his casthanks again...where can I get that Info...I needs to lean this stuff!

if your ecu plugs in then im almost 100percent sure its the correct ecu. I dont think any of the sr ecu's plugs are compatible but maybe its just the pinout...anyways when he trys to start it what happens? let us know

[Lroi]

^^^ It just turns over...strong but wont fire, its getting spark...no fuel then but fixed that, now I think he said he pulled a code 21..cas or ignitor prob I think...any other Ideas?

[S13FASTBACKSR]

so now its getting fuel and spark? it just wont catch? make sure the timing is correct. did you guys mess with the CAS? connect your ignitor to his engine harness and see if it starts up

yeah that exactly whats happening...Im taking my ignitor over and well try that...also tha cas can be twisted by hand...that cant be good & and prob is the problem...correct?

[S13FASTBACKSR]

if the problem is not the ignitor (which i dont think it is since you are getting spark) then im sure it is just the timing being off..yes the CAS being able to be turned to the left and right by hand is not good..that will retard/ advance your timing randomely since its not tightened down..its two 10mm bolts that tighten it down and the timing should be 15degrees btdc
