My "mild state of tune" opinions please.

OK....

Ill have a crack at answering this one...

What in your engine bay tell the ECU how air you are taking in..?? Your AFM.. So, a boost cut defender could be your answer or and EVO3 AFM (im sure there are better AFMs to use but this is the best one I could think of, plus i havent been 4G63ing for a while)..... Anywho, the 2 previous suggested ideas or both........

There is no real point in trying to trick your ECU. You are simply better off doing it the right way and sorting out your boost cut rather than going round it......

If this is incorrect, I know someone will correct me so we can both learn..LOL

[DjB]

Oh yeah.....

The manifold..... If you can track one down thats in good nick, why not. As everyone has already said im sure, the VR4 ones have tendency to crack.

But if you know how to weld, why not try and knock one up yourself? I did that for my Sigma. Came up a treat.....

Dude im making a dump pipe now..thats enough of a headache.
sure,i can weld..but these days making one of stainless would almost be more expensive than buying one..its alot of work in making one though...

I wouldnt even bother trying to make one unless i could get onto a tig,i got one at work...

F*ck Arc welders...sorry some frustration there,but im making my dump pipe with an arc welder that was made when jaws was a goldfish.C*nt of a thing

 

[CLuTZ]

Why bother with a SAFC, when a properly tuned chip could do it all, and get rid of your boost cut?

 

[JAP63]

You did pretty well there Jamie

With the 550's you should be able to pop in a 055 maf and not have to adjust the safc at all!!

I'm pulling my 055 off tomorrow, you can try it out if you like.

Come up to Craigs on the 4th of Feb and we can log it too.

Tim

I have a pefacelift,arent they dual board and not loggable?
Whats happening on the 4th?and who is craig?
also,will the 055 go in on a stock computer? and u think it will almost bring it back to normal?

would an Evo 0 have an 055?
also....

What percentages should i have on my SAFC2 running one bar?
i have +4 from about 5200 rpm onwards!!
dude im shitscared of detonation!! and my car dont pump out alot of black smoke..and my plugs are far from rich looking...i have a stock pump
and a stock reg...ofh yeah,im at 10 deg base timing,too high isnt it..

You can always swap to a single board ECU, chipped to suit larger injectors and 055

haha.
i just noticed this topic has been moved from where it started in general discussion.
i thought bout putin it in here.
Didnt think id spark this interest.

KEEP THE BRAINPOWERE ROLLING PEEPS :!: :!: :!:

10 is a bit high, take it back down to 5 base.

Here is the link for what we are doing on the 4th !

An Aus spec (chippable) ECU goes for around $2-300.

Ah...all makes sense than.
i may have to pay a visit.

Ok........

Just to clear things up for stupid people like myself. A stock Aspec VR4. replace the std AFM with an EVO3 item. Then install a boost cut defender. Would the boost be able to be wound up over 14psi (thats factory boost cut isnt it ??), and not run into boost cut. Or, do you need some form of editional management like a chip or expansion module to be compatiable with the EVO3 AFM.....

Cheers for clearing this up, this has been something ive wondered for quite some time....

The EVO AFM will make it run lean? For the stock VR4 ECU 550's are needed to compensate for the different AFM.
Easyist option is to simply chip

550+2gAFM = Stock VR4 ECU (Im not sure where boot cut will occur)

 

[DjB]

But if I was running a chip or some form of tuning module i would be able to run would i have to change injectors....?

Chris

 

[Entaran]

Chips are written to suit certain injector sizes, so no. PM vr4play (vr-4-play) i think on here about a chip.

if you come and your still interested in selling the 14b you should bring it with you, i'm sure one more thing to get done during the day won't matter
