Upped Boost, Er34 Experiences Power Cut

[8110]

I'm not exactly sure what is happening to my ER34 but let me describe some details.....

The ER34 (Turbo) experiences power cut on high revs. I've had it happened on 4th gear @ 5,000rpm around 130km/h and at times at lower rpm. Thus it is not easily replicable.

The car started to have these cuts after the boost was upped using HKS EVC IV. Highest recorded boost now is 0.78

The car has a straight pipe, cat-back exhaust, open pod, and uses NGK Iridium Iriway 7 plugs.

What is happening to my ride? Boost cut? Fuel cut?

Stock ECU - Rich and Retard mode...

Basically the same problem 1000's of other people have had before you - GET A TUNE

Yes it is on stock ECU.

So what is the ECU doing? Cutting fuel supply?

What can I do besides changing to an aftermarket ECU. Would love a Power FC but the cost is just too high for me now.

Go to your mechanic and get your car tuned on a dyno.

My car only runs .75 Bar due to the factory computer as the factory computer makes the do funny thiny if you increase the boodst anymore.

The other option is the get a fuel cut defender which will allow you to up the boost but you will still need to get the car tuned.

The best option is to get a power fc and enjoy running 12psi constantly and be done with it.

Fuel cut defender is not that advisable

return the car back to standard

Can use an SAFC that way you can eliminate fuel cut and be able to adjust your A/F ratios

If you cant afford the PFC then turn the boost down and wait untill you can afford it
