    Hi all, I've got a bit of a weird issue with my 3sge sw20. My idle is really high at the moment, approximately 2k rpm. I've fully cleaned, sealed, and clocked the IACV but to no avail. I have no vacuum leaks whatsoever and when I put my finger partially over the IACV, I can get the idle to...

    Hey, having trouble identifying what ratings this resistor has as the things burnt out with no markings, no readings from voltmeter either as it's kaput. All the ones around it are 1w rated and sit between 4.7ohms and 10ohms. Any information or pictures of an ECU would be appreciated.
  3. MKII, 90-99 NA & Turbo
    Hey there, trying to replace a capacitor and a resistor on my ECU but cant find an exact match for the capacitor. The one in the ECU is a PF(M) series and all I can find is a PW(M) series with the same spec. Its a 10uf 50v electrolytic capacitor (I've attached pictures). As for the resistor the...

    Hey guys. Got a few burnt out capacitors on the 93T’s ECU. C810 and C512. I’ve got the capacitors arriving tomorrow, but while I wait- does anyone know what these two capacitors do? I think C810 is for the idle, the other I’m not sure. Thanks!

    Hey, I know there has been discussions about an AltezzaLink ECU being usable for an MR2 Spyder, I have throughly investigated that article and it was quite helpful! I’ve been sitting on a Link ECU (MR2Link V2/3) whilst my turbo is being fitted. I went to fit it and it’s for a MK2 MR2 wiring...

    So I just recently bought a '03 MR2 w/ the SMT. Well my issue is that the gauges are not functioning (speedo, tach, fuel, and temp) nor are the digital readouts working or A/C button and the airbag light and check engine lights are on. I was told by the gentleman that I purchased the vehicle...

    I have a Blitz Access Supercomputer for a 90 to 92 mr2 turbo. It is tuned for 540cc injectors as well as a ct20b turbo. I bought it a few years back for my car, as I was told it would also run with 440cc injectors. While it does run with 440cc injectors, it is absolutely pig rich. 8000rpm...
  20. MKII, 90-99 NA & Turbo
    Hello, I have a 92' Revision 2 SW20 NA. It's a JDM Import it's limited to 110mph, I would like to bypass this by swapping in either a UK spec ECU or by installing a HKS Speed Limit Defencer (which is actually more expensive than just dropping in another ECU). Is it okay for me to just install a...
