Hello all,

For anyone who is thinking about modding their car, I would seriously consider engine management before you start. Last night I learned just how valuable a good ECU can be.

J-Spec Imports got me a standard ECU that has been chipped by Access in Japan. The mods on the car it came out of were almost identical to mine, bar FMIC, so I decided to give it a shot. I could not believe the difference. Boost comes on stronger, redline is achieved quicker, any misfire problems I had are now gone, and even the exhaust note sounds better! :wassup: "Snapping" 2nd gear now allows the car to go major sideways as well, something I could only previously do in the wet! :aroused: It is by far the best mod I've done!

Get Engine Management People!!!

Yeah I forgot to mention the best part.... $150!

Mods this chip is for:

*Full 3" zorst

*FMIC (I've got the stocker)

*Pod Filter (I've got a panel in stock box)

*Bleed valve @ 12psi (I'm running about 10-11psi)

The only major difference is the FMIC. Even so, my car now feels HEAPS stronger/quicker.

do you reckon it would matter if i ran it with a stock intercoller and only at stock boost witha 3" zorst and a pod?

what about the fuel differences does that have any effect do ya reckon?... i would have thought that if it was tuned to jap fuel then i would be running to rich etc.... ??? i honestly have no idea though so fill me in :)

DJ984: With my VERY brief experience I would say you'd be OK provided its a stock ECU.... but best ask a tuner who knows what their taking about.

Drivebai: I was in the right place at the right time. Its not just a chip, its a whole replacement stock ECU that has previously been chipped. I got it through the guys at J-Spec Imports. One of their clients upgraded to a PFC (I think) and wanted to get rid of the old one cheap so I snapped it up :)

better get everything checked on the dyno coz jap ecu's are tuned for better fuel than u can find in australia. Even the base tune that comes with the power fc is danderious to run with proper tune

The guy who had it before me used it here in oz so I should be right. I'm going to BMT on satdi anyway :(

Just in case anyone is still interested I had the car on the dyno on the weekend and made 153rwkw@13psi. Thats up from 140@11psi.

The fuel map is pretty rich, only marginally leaner than stock, however the ignition timing is HEAPS better hence the increase in responsivness and mid range acceleration. The ignition timing has allowed me to run more boost which is sweet coz before anything over 11psi would cause severe misfire.

Better fuel economy as well. I got 460km to this tank, and I was punchin it :) I usually get around 400-430km if givin it a beating.

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
