R35/hpx Maf Info Needed For Power Fc & Data To Tune With


Recommended Posts

  • 2 months later...

They're amazing, have tuned several cars with them already and you have very little issue with reversion when you back off the throttle on light load unlike the Z32 where I often recommend placing a few bends in the intake.

I've just ordered the higher reading HPX ones for another 2x cars I'm tuning (both on Nistune). Literally click a drop down and select the R35 AFM and pipe size.

My R32 just got done tuning with Nistune using R35 AFM as well.  But since I'm running factory size tube (65mm) and the existing VQ map doesn't go below 3", my tuner spent an hour just re-mapping the VQ map.  After he was done he was so impressed with R35 AFM that he ordered new R35 AFM for his personal R32.

all the tuning is done in the following table so you actually dont really need the data, i've had to make dozens of maf curves from scratch as we mix and match housings and cooler pipe sizes on a weekly basis.

Most people forget that with powerFC the FUEL table is only a target AF table and should not need "TUNING" (Fill in your taget afs in the INJMAP table then tune in the AIR FLOW CURVE table)

 Glad everyone is enjoying the conversion .  I've got mine on the Dyno now being tune and we are having issues with the internal IAT in the 35 MAF messing with the reading on the stock RB 26 IAT sensor. Turning with power FC and voltage jumps out of nowhere

How did you go with this mate?

Also have a GTR which is currently stock with a PFC and TBE. Planning to single sooner rather than later, but won't be building the motor for quite a while so am happy to keep it simple with the PFC. A single R35 AFM would make things super simple and dirt cheap while the cars still at a very basic level.

    • Why are you still trying to buy a crappy jap brand exhaust? go to your local exhaust shop and get a heaps better one made that will fit under the body 100x better
    • I’m very happy with my recent purchase of the Fuga but resisting the conversion to English of the navigation system. I’ve used Google translator to get around the system to date but I must have pressed something, now wondering if any Fuga owners (mine is 2011) know how to get out of this ‘dual’ or ‘panel’ screen mode. It’s driving me crazy 
    • hello! i am looking into upgrading the cams on my rb26 in the future, and wanted to start to understand what goes into this. i did a forum search and nothing obvious came up, so forgive me if this is already discussed somewhere. currently the engine is stock, save for (pertinent to this discussion): adjustable cam pulleys beefed up timing belt haltec ecu, not yet installed yet oil baffle plates i am will be converting to a single turbo set up, and that turbo's peak output is reached at somewhere between 5k and 5.5k rpm. this would be for street use. from what i understand, i should be looking at cams degreed at 272°. does that sound like it makes sense? there are step 1 and step 2 variants of these cams. i am not sure what the difference is in the to variants, so if anyone can chime in on this it would be great. i am assuming i would need to upgrade my valve springs as well. other than a tune, what would go into a camshaft upgrade? if i want to go with a v-cam upgrade much later, how does that affect i am doing now? i understand that it's totally possible that i completely missed something major here, but that's why i am posting this: i am here to learn. cheers!
    • I don't know whether you've made a decision yet or not. But left to me, I'll choose RAV4 over skyline everytime. Apart from the fact that RAV4 is a new product, skyline is an old product that it's almost out of vogue. It has some issues and require high maintenance. 
    • Ill see how this adaptor goes first. But thanks for the offer.
