and will a safc fix it?

i have been told of people having problems with fuel and boost cut due to fmic while using a stock ecu.

any help appreciated.

I've got the stock ic and recently ran 14+psi (15psi spike) no fuel cut issues.

I think if the ic is sized very well the extra horsepower potential may exceed the Air Flow maximum allowed by the stock ecu. More hp = more airflow = ecu dummy spit.

A big ass ic will create some lag if its oversized for the turbo and reduce overall flow efficiency. If you are running an ic rated a 600hp and you have a 300hp turbo you might make less power than stock AFC or not. Having said that at least if you decide to circuit race you will keep the power at maximum all day.

rev you make a good point that alot of people dont really under stand. having the biggerst cooler isn't great if you only want say 3 or 400 hp my cooler is (core only) 500 x 280 x76 if you look at most of the apexi etc coolers they are are similar size untill you get up to the big one for 600 hp +

Yep, sounds like you have a very sensible sized ic megs. Building a "whole" performance package is the best way to go. Make a plan out starting with what sort of measured performance you want and design the car around that concept.

If you want a turbo that can wack out 200rwkw then get the kit that will do that with the best efficiency and you will get better mid range power (what is needed on the street).

I very much agree, howeva a big ass intercooler looks SIK! You know how much i'm into looks Megs! :)

The restrictiveness of the IC can also relate to its cooling abilities though right? I mean a very unrestrictive cooler may not cool very well cos the air goes through too quickly??

      From when I was looking at getting the 86 engineered for the turbo, the joint said to put in a few euro 5 or 6 cats, then tune the car on a nice clean E85 tune When I was looking at a turbo for the MX5, it was basically the same thing, a couple of cats and a nice clean tune Although, it will depend on the year of the Jeep IRT emmisions standards required, and what mods are done, especially if it has a newer engine installed that requires a higher Euro

      Yeah - but it's not actually that easy. There are limits for HC, CO, NOx and particulates. Particulates shouldn't be a concern in any petrol engine unless trying to comply to the very latest Euro standard. But getting a tune right so that all the others stay within limits AT THE SAME TIME is not a trivial exercise. You couldn't possibly get it right by just guessing at the tuner's dyno, unless he had a 4 gas analyser up the pipe, which is not often the case these days. It used to be. Every decent shop that did "tune ups" (as opposed to tuning) would have a 4 gas analsyer. Perhaps there's still quite a few of them around these days. But most "tuners" are only watching O2 and power readings.

      Slight segway but the most expensive part of the whole thing which I would have thought would only be required for an engine size/type swap, not a VIV test, is emissions testing.  That's when you get into the big bucks.  I can't remember the exact price now but I got quotes for the GT-R based on swapping to RB30 (not that anyone bothers doing it legally anymore...) and it was around $4500 just for that alone.  The guy that does them manipulates the tune on the vehicle to make sure it passes.  The cheaper option is to book into Kangan Batman Tafe (I think that's where it was) and hire their tester.  Allegedly you're not allowed in there with the car though so not in a position to tweak anything to make sure the vehicle passes.  I'm sure in this day and age of ultra tuneable ECU's you could get the tuner to program a special efficiency (clean) tune that emits the lowest amount of particulates possible that would pass the test.  It might only make 50kW's but as long as it passed who cares!

      I'm sure he has left signs, or, he is looking down, laughing That's my cunning plan for when I leave, lots of half finished projects, with no rhyme or reason of where I was actually up to, just to keep everyone on their toes

      Does that price include the rack time to straighten the frame and body and replacement of parts and paint, as well as the noise and emmisions testing  The last engineering certificate I had done, albeit about 15 years ago, was around $1000 for a few inspections and the certificate
