Stage 1 mods complete still getting fuel cut @ 1.2 Bar! Hi Anyone reading this Thanks in advance as its becomming rather frustrating now,
Started off with a bone stock Evo 4 import.
Mods i have done
2.75" downpipe
3" de cat
3" cat back
Orange top 560cc injectors
Black plastic cased Evo 5 ECU
New 0.8 bar wastegate actuator (As old one didnt hold pressure and made the car run 1.5 bar of boost and fuel cut)
Genuine Walboro 255
Re wire to new 255 inc relay
Gizzmo Boost controller and 3 port Mac valve (Plumbed with port 1 & 2) Side and front)
3" mushroom induction kit
Fully serviced Inc new fuel filter but running denso iridium plugs, Gap seems around 0.8mm? is it worth having a better grade or different gap plug?
After all of these mods i am still getting fuel cut when it spikes to 1.2 bar so i have to set around 1.1 bar. I am guessing that the ECU stock Fuel cut is coming in? I have the gain on the Gizzmo MS-2 set at 50, have tried all else and cannot seem to stop the boost spike, Air temps pretty low this time of year circa 5c during testing.
The Gizzmo is also set to Open loop, I tried closed but it will not run more than 0.5Bar Maybe i have my ports plumbed in wrong?, But it was as per Gizzmo instructions although they are questionable as it tells you 2 secs to hold buttons when in fact its 5 secs...
Is it advisable to wire in the FCD from my Gizzmo, Or to be safer and buy an AFR gauge, Or as i already have it to fit an adjustable FPR? If so what sort of PSI at idle Say 38PSI??
What exactly is envolved in re mapping the car, A new wire into the ECU loom? If so anyone got any links or clues on this? Is the re flash something i can DIY?
Sorry for all the Q's and await any help given :blush:
