does anyone know how/why 3 Vortech FMUs would go bad on my car? throw out ideas....cause im completly lost....and tired of having to deal w/ them.
im currenty saving up for a Link ECU (stand alone).

 

how are you certain they have died?

 

done multiple tests on them....and was at RRM for 1 of them

 

bump

 

defective or bad installation of recalibration kit. there's not much to them.

 

they were 3 new FMUs....and Rob @ RRM and I insatlled the last one.

 

bump again....i know someone out ther has some ideas....

 

Do you have a fuel pressure gauge on the car? It's hard to troubleshoot problems with so little info.

 

ot
just wondering, do you still live at FT. Lewis or moved to Texas?

 

back in Texas....and for the fuel pressure is not rising...i have Wideband 02 and EGT gauge that confirm both. i just need to know reasons on how an FMU would break. to much pressure? a leak ? what?

edit.....the last FMU has been in my car for about 1.5weeks.

 

I want to know if it ever WAS rising. It may not be the FMU's. You could have a different problem. I think your fuel lines would blow before your FMU no matter the pressure. But if your fuel pressure NEVER rose like it was supposed to...something tells me the FMU wasn't the issue.

 

yeah at RRM when we hooked up a FPG it never rose....then when we chaged the FMU the pressure rose. witch told us it was the FMU....but now this one has gone bad. if you have any idea on what id should check let me know....cuase it might not be the FMU breaking but somthing to cause it to break.

 

That's what I'm thinking. If a part fails once..maybe twice...probably poor construction. But more than that and there's definately something else causing it to fail.

 

suggestions? anyone?

 

**** vortech fmu's they are ****, mine failed on me and it caused me to detonate 3 times, i still have compression but im in the middle of finding out if it caused any other serious damage. **** vortech.
