What Shoud I Do

[sav man]

As some of you might have read, one of my AFM's is dead (i've cleaned about 2 tonn of crap out of it, but i think it's been mistreated in the past)

I got a price for new RB26 AFM's ($800), I thought at that price it's a good exuse to change ECU and get diferent AFM's. These are the options that have been put forward to me.

my idea: Get 2 Nismo AFM's, and a Power FC.

my mechanic want's to put a Haltec on with a MAP sensor.

if i was going to go MAP sensor I was looking at the Power FC D-Jetro.

I've read that MAP sensors on GTR's are a real pain on a road car, so I'm leaning more towards the Nismo AFM option. And if I was going to spend up and get a piggy back MAP Sensor ECU, i'd do it properly with a Motec.

Anyone have any better idea's?

I see the dilemma - problem with Speed density based computers on cars with multiple throttle bodies is finding a good vacuum signal. IMHO I wouldn't use a MAP based computer in the quest to save a few hundred, I would use it at the point that they get too restrictive or a drag car situation where it only see WOT. To get a MOTEC with all the options, idle control, cam control ect installed and tuned your looking at over well $5000.

Best bet would be to get a couple of Z32's as they flow more are a much more linear items then the standard MAF's and get a PFC. This tuned would be around the $3000 mark assuming everything goes right.

get the Nismo items, direct fit

then get a PowerFC... while your at it find a reputable tuner who will work with the PowerFC

First ask yourself if you need tuneability and plan on doing other mods, because if your happy with the current power you have, you cant beat a second hand AFM for $100 and everything runs exaclty like it did before and is legal
