Hi all.

Ok. Just a short dicribtion about my car.

R32 gtr with a 26/30 engine with 2871-10's and a ViPec plug in.

This light is under the ABS light. It has what look like an exhaust pic and 3 wavily line above it.

This light only come on when I'm on high boost (19-24psi). But I can track it all day on low boost (15-17psi) and it will never come on. It only stay on for about 1-2 seconds. It go off when i take my foot of the accelerator. It does the same thing on both 98pulp and e85 tune. It did not come on when it was on the dyno.

So I just wanna know if it is an exhaust temp and is it had for my car?

I'm pretty new to the whole gtr thing.

Thank you for the help.

lol in a 32 thats the engine light!

i dunno what the go is with the vipec but with powerfc that can serve as a 'knock light' on the dash.

the fact that its coming on, only under high boost, only when youre giving it stick points to a few things...

I believe it doesn't come on till after 400C. It's really just to let you know the exhaust is hot enough to ignite grass. But it can serve a purpose on a modified car though, it could be that your cat might have collapsed or partially blocked. Though with those mods listed and the light not coming on at the track or the dyno, it just could mean your tune or specifically the low-mid (cruise) areas of your tune are lean.

vipec use that cat light as a check engine light, so what ever alerts your tuner has set up to trigger the light. Could be anything from overboost, watertemp etc... By the sounds of it most likely overboost. Speak to your tuner about it.

I brought the car with the computer already in it. Rigoli only tune it for E85. He did not see thelight come on on the dyno. I don't know who wire the computer up. But it is a plug in so it should be what ever ViPec wired it up as. I might have to call up ViPec to see if they can help.

    • Order for the 2025 model R35 GT-R were accepted from 3rd March and 26th August the last order rolled off the production line at the Tochigi plant. Concerning the R35 GT-R replacement, current Nissan CEO Ivan Espinosa said "Nothing has been decided about the GT-R at this time, but we are well aware that everyone is waiting. The GT-R will evolve and reappear in the future. Please be patient until that day comes." Nissan has a lot of issues with management and finances so take Espinosa's words with a big grain of salt. From what discussions I've had and read about here in Japan, not a lot of people are confident about Nissan's future, let alone the next GT-R. 
    • Thanks. We getting some parts along too so he will be solving the speed issue like next week so i will let you know what he came up with.   
    • 21 is explicitly the coils detected as the issue. Is it guaranteed the actual issue? No. Just the ECU thinks it is. When you say rattling, describe it better, get an audio clip as best you can if possible.
    • Yea got me coppers. Bad news is I just put them in and the car still has the light and shakes. I also noticed I hear like rattling coming from the exhaust piping right under me. Does 21 also have a possibility of being O2 sensors?   So, coil packs are good, the harness is good, the MAF is working, and obviously the spark plugs just replaced and working.
    • Make sure you drop the GTT base tune back in, and set your injectors again, this will remove anything playing up with it you may have removed. Possibly lean there as it's normally a fast transient going THROUGH atmospheric pressure, and a turbo motor would then quickly go richer as boost builds. The only worry you MIGHT have is ignition timing, as the DE is higher compression than the DET from memory. But again, you're not in boost, so the DE motor will be a lot more forgiving at atmospheric.   Get Murray, Kinkstahs, and Johnny's input on tuning haltechs, those guys have played with tuning enough in the past to be able to help now you're past the trouble shooting stage of the MAP issue
