EVO X not making any power on WOT
I hope someone can help me.
My evo X does not make any power on WOT
If I gently and slowely go push the throttle it makes good power and there are no problems at all up to the hight rpm range.
But if I floor the throttle the car backfires and makes no power at all :-(
I have been reading lots of threads and already changed the following things:
- New sparkplugs
- New FPR tube
- New MAF sensor
But the problem still remains.
I also ordered a new fuel pump relay - hope to receive and replace the old one today.
But if this does not solve the problem i'm out of options as how to solve the problem.
Did some of you have had the same problem ?
Any suggestions how to solve this.?
Thanks Martin

This sounds tune related. I would ditch the Ecutek and get an open source tune. Throw RAX fast logging patch on there and log to see what is going on. Is your BOV venting to atmosphere? Your tune needs to account for that too.

Changed the fule pump relay this afternoon but unfortunately without any result.
Also replaced the AEM intake by the original one - also without any result.
The BOV is a Turbosmart that's recirculating at low pressure and vent to atmosphere at higher boost.
I'm running the BOV for 5 years without any problems so I don;t think this is causing the problem.
But just to be sure I'll refit the original one tomorrow to see if this works.
I have contacted my tuner and will he place a 3 port solenoid and do a remap - I hope this solves the problem.
When we are at it we'll go for a map with pops and bangs :-D

Update:
I have visited the tuner and we replaced the boost solenoid by a 3-port solenoid.
He installed a map with pops&bangs but unfortunately the problems with WOT are still there.
Now I know for sure the problem is not overboosting !
.
The tuner informed me it might be a coil pack that caused the problem.
So I bought a new coil pack and installed this but the problem still remains :-(
Could the issue be injector related ??
Am I the only one who has encountered this problem ?

Today we found out that the Map sensor does not work. (The sensor always shows 100mbar this does not change while driving).
So I ordered a new one (4bar Omni-power Mitsubishi map sensor) hopefully this solves the problem.

Is the car misfiring? Did you check all the spark plugs? It might be worth pulling them out and making sure the tip still exists. I have destroyed one spark plug before. The car would cut power and stutter if you attempted to apply much throttle. Makes a d-d-d-d-d-d sound. Could be another ignition issue as you mentioned, coil pack etc.

No problem.
Until now i have replaced:
- Sparkplugs
- Coil pack
- FPR tube
- Fuel pump relais
- MAF sensor
- Solenoids by a 3 port solenoid including all tubes.
- Map sensor
- Mounted the original intake
- Mounted the original BOV
- I went to the tuner and he did not see weird thing in the mapping.
But he cannot make a new mapping for the 3-port solenoid as we cannot use full load.
In his opinion it has to be an electrical problem.
The weird thing is that the ecu does not show any codes :-(
We did all the thing mentioned above but the problem still remains :-(
It's really frustrating so I'm going to bring the car to an EVO specialist
I cannot keep replacing parts and hope the problem dissapears.
When the problem is fixed I will make a post.
