r33 ecu just needs a daughterboard soldered to it to fit the rom/emulator

r32 can be rechipped without an additional daughterboard and can be made to work in an r33 i.e. switch 2 inj wires and add the r33 vq maps etc. - feedback loops are all crazy but?

Many people have asked to me about R33 remap.

Thank you

OK.

When your car has been boosted up (normally over about 12psi but some cars only 7-11psi.) with air flow meter being near 5V, RB25det ignition timing map will retard.

As a result, engine misfire and engine cut will be experienced.

I have three remapping options

1) REMAPPING FROM DYNO SHEETS AND CAR MODs.

After receiving your dyno sheet (I need AFR and rpm) I will remap chip accordingly and send it to you. Original chip will be replaced with remapped chip on ECU.

As soldering 84pin chip is difficult, you probably need to find a soldering ship. eg; TV and video repair shop.

Or, I could fit remapped chip to my spare ECU then exchange it with yours.

Also I could fit remapped chip to your ECU.

*please check on dyno again when you get the chip to ensure safety.

*Please Check and adjust ignition timing, AFM (many cars fault), O2 sensor before dyno.

Advantages

Able to remap in all states.

Obvious increase in power.

If your car becomes too lean or pings after fitting my chip, I will make another chip.

Disadvantages

I’m able to remap up to intercooler, bigger turbo, fuel pump, Z32 AFM.(I can not remap to full tune engine.)

You will pay dyno fee 2 times.

Dyno shop may charge for checking and adjusting ignition timing, AFM (many cars fault), O2 sensor before dyno

Price chip only from $350 (std turbo)plus post

Exchange from $400 plus post

2) REMAPPING ON ROAD

I will fit wideband air fuel ratio meter, and rap top computer, modified ECU for real time remap, emulator and map tracer.

We (you and me) will go for a road test then I will remap ECU real time.

Advantage

Remap will be adjusted to real driving condition. (Its real load and window for intercooler.)

You’ll be able to recognize an obvious difference in feel when driving

Free checking and adjusting of ignition timing, AFM (many cars fault), O2 sensor

Cheaper price than dyno tune.

Disadvantages

If you are provisional driver may be dangerous.

You can not see exact power increase

If your car has a lot of power I can not road tune-danger factors

Price from $450(std turbo)

3) DYNO TUNE

Advantage

You’ll be able to see exactly, how much power increase.

Safer than road tune. (No accidents and no police)

You do not need drive.

Free check and adjust ignition timing, AFM(many cars fault), O2 sensor

Disadvantages

You can not check drive feel.

You will pay tune fee and dyno fee.

Price from $500 plus dyno fee(std turbo about1- 2 hours $90-180)

I tuned his car about 3years ago on the road.

His car made 196Kw at 8psi.

Power will increase about 15-20kw.

Some cars over 30kw more. (FMIC is very important)

This is R33 A/T dyno sheet.

33kw more.

(red) Std boost (7.4psi) std ECU.152kw

(green) Std boost (7.4psi) my chip.abou 170kw

(blue) boost 11psi my chip. 185kw

flash-tune of a factory ECU only makes sense if you never plan to mod your car again

by saying that - I'd be taking my pride n joy to a well respected tuner with aftermarket ECU :banana:

      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.

      R34 25GT Engine Light 21

      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.
