Best JDM ECU forAlmera GTi N15... Im having Issues with NATS
Hi Guys,

I have a question which I had asked in the Almera owners club UK forum and did not get an answer and hoping to get an answer here.

I have a year 1998 Nissan Almera GTi which is coupled with an SR20 Lowport but immobilized! I am thinking that its not easy to remove the immobilizer from the ECU itself so, should get a replacement since the country I live in (Malaysia) is heaven for halfcuts (whole front cuts of JDM car's engine, dash and etc)


I can help by giving you guys some information of what I have gathered.

A Picture of the engine bay..

Not exact but also an Almera GTi SR20 immobilized ECU part no F3 A18-E86 A09 Made in Japan. Mine should be the same.

And MY Air Flow sensor Part No as printed on the unit read respectively from top to bottom is..

22680 27200

I did not manage to get the TPS sensor Part no. If you need that, i will get it when the sun is up tomorrow morning.

I am assuming probably a 1995+ G20 or P10 or P11 ECU might fit since the engines look alike. I am not sure and I turn to the GURU's for help.

Please Help.

Thanks Guys!

P/S: I have done my research both here and there but I just could not find anything.

Honestly sounds like the same issue P11/B15 guys have with the 32bit harness and ECU. Check out this write-up from Vadim:


I know the 00+ P11s have the immobilizer aswell, I can only assume it would be the same issue. I have a 99 P11 so I don't have any personal experience with it, just brain storming. I know guys who do a DET or VE swaps into 00+ P11s also grab a 99 P11 harness and use an aftermarket ECU as the 99 P11s where kinda a bastard child between the P10s and 00+ P11s to where it used an older style harness but still used the 32bit ECU, I believe the 98-99 B14s are the same way. If you wanted to keep your car OBD2 I would suggest you get a later model B14 harness or a 99 P11 harness, ECU, intake manifold from an older lowport(will bolt up to your RR block) and MAF. Little bits such as the IACV, ARV and TPS will be different but if you swap intake manifolds you will need the older sensors anyways.
