How to: Z32 AFM into RB26dett

[rb25dett]

Hi all..

Z32 AFM connections are marked A to F but only four connections are used to the RB26dett... How to loop those wires and do I need to remap?

Thankz

Yes the two pins are not used in the Z32 airflow..Wiring diagrams could be found in the net, with a bit of searching. Yes..an extensive amount of remapping is required inorder for it to run smoothly..even with a Power FC with its air flow type conpensation, you still have to do a bit of remapping.

IMHO switching to a Z32 airflow isn't worth the effort if you running on stock everything ..infact the stock airflow is good for 600HP (engine).

Today I install 2 Z32 AFM c/w wiring and new 4" HKS Filters. The first run seem to be smooth. Then the engine start to knock. I believe remapping is required in order to run smoothly.

At present I'm using HKS GCC (PFC-F-CON-S) for adjusting air/fuel ratio. If possible, I want to adjust air/fuel ratio manually to defeat the problem before remapping by w/shop

So, what should I do with the adjustment (16% rich TO 12% lean) on that HKS GCC. Better to be rich or lean to fit Z32 AFM.

BTW, I'm gradually upgrading to 500HP (wheel)

Hi rb25Dett:

It would be a tall order to attempt to tune the car without an exhaust tempt meter and a wideband lamda sensor. It is not too safe to assume that if the engine is knocking ,its most probably running too lean. There are a few other possiblities why an engine is experiencing knocking or pinging. However, if I had a choice of running too rich or too lean, I would most probably say run it rich..however in the long run it'll tend to eat up your plugs and even worse causes 'cyclinder wash' which cause damaged cyclinder bores

However be warned that when knocking could be heard its usually means serious engine damage is in progress..an engine could take a certain amount of knocking but when it could be heard, its serious.

Dude, when it comes to tuning, try not to cut corners too much...It'll cost you more in the end. So I suggest you get the car tuned ASAP or not drive the car around before getting it tuned
