Hi....

I have a big problem....
I have just put the HKS T04R kit on my FD and also street portet the motor but now when i startet it makes fuel cut in about 3500-4000 rpm...
I have removed the airpump and the vacum hoses....
It runs ok until it comes to 3500 rpm and then it backfires and just cutting the fuel...
Is feels like it runs on a emergency program so it canīt rev over 4000 rpm....
There is fuel pressure and the map sensor is working too...
I donīt know what to do now..
Can anybody help me please....????


Thanks

Are you saying your running the stock ECU on a street ported motor with a single to4r? Scary thought

Please list all of your modifications, including which ecu you are using to control the car.

I wonder if he has one of his secondary fuel injector plugs unplugged. ...

Hi...

My mods are:

Hks frontmount intercooler
Hks special full turbine kit T04R
Hks AIC injector kit
2 x 1000 cc injektor
550 + 850 cc
Fuel cut defenser
Hks evc boost control
Fluidyne radiator
Hks clutch/flywheel
Hks twin power ignition
Hks Hiper muffler
Hks front pipe
Hks blowoff valve

Is there anything more you need to know..???

If i go easy on the throttle it can go to 4000 rpm but if i go hard on the throttle it cuts right away....

thanks

I still think a secondary injector plug is unplugged or there's something goofy w/ the secondary injector driver. It makes sense.

I may not know what I'm talking about but I dont see an aftermarket computer in you list of mods.
and also 2-1000cc additional injecters maybe you have too much fuel and no way to control all of it.

Hi....

I think you maybe is right.... We have now found out that the secondary injector does not open.. But there is connection to the electric wires so there is some problem somewhere up to the injectors.....

The extra 2 x 1000 injectors does not open until 0.6 bar so that is not the problem... It is fuel that is missing..

Thanks for the fast reply.....

I am in a hurry because I am going to a show called "The fastest car in Denmark" the 7/8 june and I hope to win...
There is a Supra with 800 hp i want to beat....
