Hey fellow UTEC owners need help here! ok i'm running perfectly with my evo but when I lay 100% throttle my boost gauge tells me i'm hitting 25psi and then of all damn things I HIT FUELCUT with my walbro 255! i adjusted the boost map from 75% to 70% @ 3000rpms all the way to 7500rpms. the thing is that it dropped the boost down to 20-21psi on map 1 which is what i wanted.. no more fuel cut nada, did multiple runs to confirm holding 20-21psi ... but got back in the car later tonight and got on it.. and hit 25psi again and got fuel cut.. i saved the adjusted map so i dont know why the hell it did it! it should be told though on my turboxs bleeder valve.. i lost the little adjustment screw... could this be causing my problem?? if so where the heck do i get another one?? i've been to the local hardware stores and even NAPA and AUTOZONE... the thread is so fine can't find any screw at all that will fit

 

Email malibujack. He's the utec guru

 

did that but thought i would get opinions about the bleeder valve screw and see if anyone has an extra one per chance....

 

This happened to me, and i found the correct screw at a hobby shop , it ended costing me $1.00.

 

Have you checked your injector pulse width lately?

 

Wait, the adjustment screw can fall out on it's own?

 

ya, it can if you loosen it all the way out... which i did when 1st installed UTEC system... whoops

 

Be sure you boost gauge is tap in the right spot. I had this problem but no fuel cut with my gauge a while back. The gauge would read 25-27psi at full boost but once I taped the right spot it now reads the right psi. This might not be your problem but its somthing you might want to look at.

 

thanks for the tip, but ya i tapped it in the right spot, once of 1st mods lol

UPDATE: ok either i have a quirky UTEC or i was dreamin last night... got oil change, rotation yad yada whole 100yds today... took it out and damned if it was hittin 21-22psi running perfectly! i'm gonna keep an eye on this though... really weird

 

Ooh, you neglected to mention that the screw is missing.. you will basically have no boost control if its missing.. But if you find your able to fix it.. and then it comes back, it means the UTEC may be in program mode instead of run mode.. Check your PM's I replied..

 

I PM'd ya back, so in other words.. find another screw

 

well did what Malibu suggested so find out later tonight how it works.. keep your fingers crossed!
