Condition/health of your engine
Year - in your other posts you were talking of a fcd so you must have a rev 1-2
And mods you have. Do you have an upgraded intercooler? metel head gasket?

Uprated intercooler thats it

Hi does anyone know what a safe boost pressure would be to run on a stock engine and turbo. I have heard that rings are good to 1.2bar?

Re checked map sensor put about 10psi through it and got 4.3 volts so its all good was just dodgy connections. soldered them and problem solved

Ok I have replaced dizzy arm and leads and missfire is cured yay. Also cured fcd fault must of been dodgy connection as I have soldered all connections and its spot on. Thanx for everyones input

sorry about that new to this lark wasnt shore i was doing doing it correctly

I have ordered dizzy arm and leads as a precaution. Would a faulty arm cause fuel cut like symptoms?

Even with fdc disconnected im still getting a lean missfire under load and complete loss of power like a fuel cut. And when fcd is connected stock boost gauge goes to max with ignition on with engine off. I am getting 2.5volt signal with no vacuum and it drops to 1.3volts with about a 1 bar vacuum. ...

Was thinking the same thing although im still getting a miss under load and a complete loss of poer sometimes which makes me think its the map sensor any thoughts?

Ok thanx I was told that the plugs and dizzy was replaced shortly before I bought the which was not even a month ago but not shore about rotor arm will get that replaced. I disconnected fcd today and also bypassed manual boost controler but still getting same issues. Although today it was like i got...

Misfire under load is normally ignition related. So disconnect FCD, and sort misfire first. I assume you know when you last replaced the service components, i.e. plugs, cap and arm? If not, or there is any doubt, get them replaced. Also, leads and coil degrade as they age. Ok thanx I was told that ...

Yeah it is indeed, HKS Fuel Cut Defender, taps into the signal wire from the turbocharging (boost) sensor to the ecu, modifies the signal to change fuel cut from ~12 psi to ~17psi, in-conjunction with an electronic boost controller currently set to 14 psi. Hi I have same issue I have developed misf...

Hi can anyone please help. I have a problem with an hks fuel cut defender. when it is wired in The stock boost gauge will rise o maximum with ignition on and engine not running this never happened before. It has only happened since I have developed a misfire under load. If I disconnect fcd stock boo...

Will check for error codes shortly. Now i have turned down the boost the after market boost gauge is reading about 8psi. cant see anything obviouse with pipework but will get it smoked checked on tuesday. Have checked for error codes and im getting 34 and 35. Excessive turbo pressure and open circu...

Hi can anyone please help. I have recently bought an mr2 rev1 turbo which has had an uprated intercooler manual boost controller and hks fuel cut defender fitted.
