How does Ecutek interface with MIVEC? I've got pressure problems
I think that this question will get better exposure here. So...
Reguarding the MIVEC parameters, what all is changed when a guy with a IX goes the Ecutek route. The reason I ask this is because it seems as though my IX has had problems relating to the oil system that the MIVEC uses. It seems like there is too much pressure or something. I've now got a "service engine soon" light and a P0011 code. The car is currently at the dealership and I'm scared to death that they are not going to honor my warranty. All I'm running is a full exhaust and an Ecutek.
The car runs fine, it just has a service engine light. There is no knock or hesitation from the engine... the response and power still seems to be there. The only thing I'm wondering about is whether or not the oil pressures are going outside the normal parameters because I'm running a more aggressive Ecutek program.
The engine had a leaky oil problem from the beginning... originating from the oil supply line to the MIVEC system. Well, the timing belt got saturated... they replaced the timing belt... and a day later I'm seeing this P0011 code. The mechanics said that they didn't have a "service engine soon" light when they were done with it. They also said that the car popped the code when I was at like 3,500 rpm at 35 mph (black box stuff). Yeah, scary stuff... they can detect almost anything that you did wrong. Luckily, I did nothing wrong to cause this.
So, can a reflash cause the engine to run higher or lower oil pressures that are outside the normal parameters and thus throw a code?

The Mitsubishi mechanics said that the timing belt and cams were put on correctly and that my problem seems to be related to a oil pressure discrepancy because the computer may have noticed an improper pressure figure at that certain point. The ecu didn't like it so it threw a code.
I'm just trying to figure out how to fix the problem. I have no where else to go but to the Mitsubishi dealership to fix it. If I owned an Evo VIII, this would probably be an easier problem to fix. Unfortunately, they now know that I have a tuned ecu. They are going to try to fix it under warranty though... I'm keeping my fingers crossed.
The code that I pulled up by going over to Advance Auto Parts said this:
DTC (Codes)
P0011
Camshaft Position
Actuator A - Bank 1
Timing Over-Advan.
DTC Pending (Codes)
Camshaft Position
Actuator A - Bank 1
Timing Over-Advan.
The Mitsu mechanic said that I can't trust what the Advance Auto code reader says... but why not? What makes one code reader more accurate over the other. If the ecu is throwing a specific code... what makes it wrong if the code reader didn't come from the Mitsubishi's shop? A code is a code to me.
Edit: The oil light flickers intermittantly next to the SES light. I don't have an oil pressure gauge, so I don't know what pressure I'm seeing when it light's up.

maybe it's your cam angle sensor acting up. either way let them handle it. Worse case scenario if they can prove (key word here is PROVE) that the flash caused the problem then have Vishnu take a look at it. And as for lesson learned slap on an Oil Pressure reader next time.

Mmelmann...I once had a conversation with Shiv and (my best recollection is that) he mentioned that when the MIVEC is reflashed to operate outside the original parameters...the ECU may throw a code. The code can be reset by anyone that has the tool. It will continue to reappear until an ECU "fix" is devised.

The problems with the VW's are the oil pump screens get plugged up from lack of oil change's (not you).
Problem is when the oil pump can not make enough oil pressure at the cylinder head and the chain adjuster can not adjust the intake cam accordingly. The elecrical signal is sent from the ecm to the solinoid valve on the adjuster to control the oil pressure.
Or the electrical valve inside the adjuster gets shorted and throws the same fault.
Seems how at times the oil light flashes, I would have say the oil pump is bad
You have to remember I am german smart these jap cars are new to me. I don't know exactly how MIVEC works but it is proly like it is on our 24v VR6's, or an M3.
Just my 2 cents.
Keep us posted I am very currious as to what it is.
