Afm Recalibration?

[No Crust Racing]

In preparation for a swap to GT-SS/-9s, I'm looking at AFMs.

Has anyone done this?

I think Racepace use this guy to do their AFM's both reconditioned and that.

Good to know, I have managed to find history of others on here using the same place.

Seems they must go OK.

If the stock ones work fine - sell them, buy brand NEW Nismo.

Will work out to be basically the same price as that reco price (plus each way delivery etc)

They do work, I was just forward planning for turbo swap.

I understand you "can" go beyond 300kw with standard AFMs, but life is easier with the Nismo units.

I didn't think stock AFMs were worth much? Aren't the Nismo one's 4-500 a piece?

why not move over to a R35/HPX AFM?

would work out cheaper too.

Also for calibration:

Those R35 MAFs are cheap. Never seen those before. So you mount 2 of those to generic pipes and bolt to the airbox, get some plugs and rewire the loom to suit the plug then tune?

How would they go in 65mm pipe though, same as the Nismo ones. As I've got an ARC induction box and will likely stick with that or go a stock airbox.

$350 each from Perfect Run before postage and stuff. Easier to bolt on the Nismo's as they directly replace OEM, plugs and everything are the same if you want to keep AFM's. An alternative is to get an ECU that uses a MAP sensor and just keep the AFM's on there inside an airbox so it looks factory.

Doing some more reading, seems to be a LOT of conjecture and I can't seem to find any tried and tested process for using them on an 26 with a PFC and in standard size AFM pipes.

Still more than just having the standard ones re-done. Postage is free for me (when sending).

I also already have the PFC.

Using the R35 AFMs in any size pipe is trivial with Nistune. You just create a suitable VQ curve. You are supposed to be able to arbitrarily make an AFM curve in the PFC too, so it shouldn't be a hassle. There was an extensive discussion on this exact topic on here a year or 3 ago. Search it up.

I wouldn't be tuning it and given what tuning options I have locally will stick with the easiest option as I dont have racepace down the road

I might have a chat to some local tuners.

Should go map

Having this same dilemma but with R32 GTR...

Have emailed the contact you linked in your original post with a few queries and now just waiting for a reply...

[No Crust Racing]

Let me know how you go.
