Again sorry for asking but i have noticed that my R32 GTR has what i thought to be QF45 AFM installed on it.

I thought that the part number for these is A36-000-P60.

When i checked mine it had a part number of A36-000-J60 are these suitable for my car as i have no idea if this could be effecting Air fuel ratio's.

regards

post-28646-1150341290.jpgThat is a good question!

Yes it runs fine but i know these were just put on when i got the car. I think i will just be safe and will get the air / fuel ratio checked later this month as i am still waiting for my 320kmh speedo to show up before i run it again.

Are they the correct type to be running? or should i just get other as i dont know if these units are speced to operate in the correct voltage range and it is worrying the crap outta me that they are wrong for the car.

yep, that's an rb20det afm

it's not the correct type of afm, to run it properly, the ecu needs to be remapped. If the car runs fine with no noticable problems, then it probably has been remapped or has a piggyback ecu of some description (eg. SAFC, emanage etc.), or full aftermarket computer.

get it on the dyno asap to check your AFR's (it's a good idea anyway once you buy a car to check afr's), but if it's running without any noticable problems then you are probably ok.

how is it set up with the single afm? are there still 2 intakes and one afm on one of the intakes and no afm on the other? or do you have a single intake system setup? or do you have 2 x rb20det afms?

rb20det afm's are better than rb26dett afm, so it's probably been done to allow for better piping.

Merlin,

thanks for the help i really do need it.

No is has 2 of the buggers still in the orginal positions i would hazard a guess.

The car pulls like a train and to date it has not given me any problems that i know of. But as you say i will try and get the air / fuel ratio checked which is not easy to do over here as no one knows much about these type of cars. Would be heaven if i could get Pfc and have it tuned but its not to be in this part of the world.

The ECU looks like its standard to me but the seals have been opened .

regards

getting A/F ratio checked shouldn't be too much trouble. Just go to anywhere with a dyno and ask for a "power run with AFR printout". They will put a wideband o2 sensor in the exhaust and log the AFR while doing the power run.

I'd say it's been remapped. If they handn't, you'd probably feel it driving, if the car would even start at all. Maybe ask the previous owner what he did?

This is probably good! it means your car probably have a tuned ecu, and rb20det afm's are much better than rb26dett afm's

but in any case, unless you can find out from previous owner, go get a dyno run asap.

Merlin,

I will make that the first this i do when i get to install the new speedo.

I have no chance of tracking down the old owner as it was brought from a huge import yard, about 10,000 cars there. But now that is mention it run like crap for the first few hours but came good after that. Could that be a piggy back ECU in learning mode, as i know these AFM were installed after i showed interest in it. Could i be that lucky to re istall the RB20 AFM if it was mapped for them ?

Nope they are green and 80mm id so i reckon they wil be from RB 20. Which is ok just a long as they are calibrated to run on a 5 v signal. I will then have the air / fuel ratio checked ( hopefully ).

just a question i noticed their was a K band trim on the ECU would i be right in saying this is for adjusting the fuel.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah 路 Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline 路 Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz 路 Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
