fuel pressure EA82T

Dubcrazy · Post by **Dubcrazy** » Wed Jun 24, 2009 9:17 am

on my EA82T when ever the fuel pressure gets to 40 psi it leans out really badly. Its running the standard reg( tryed a malpassie but the same) with 60cc over sized injectors. Have tryed upping the pressure but still at 40 psi it leans out badly. Its running a microtech lt10 so we also tryed the map's but once again the same affect. it makes no sence to me so anyone got any ideas at all??

steff..........

NO. You are playing with more than what I have. With all std, I observed my failing fuel pump pressure drop on the road as soon as load and boost came on. Dropped off 36 psi down to about 15 - 20. New VL Bommodore pump held pressure to 36 psi and fixed problem

I had similar issues, but was caused by gummed up injectors.

As the pressure rose, the pintle had more resistance and therefore couldnt move as quickly and it was causing it to lean out.

Got my injectors cleaned and hey presto, no more leaning out.

Fuel pressure should be 36psi at idle with the vac hose disconnected.

FIXED!!!!!!!!!!!!!!!!!!!!!!!

it ended up being one of the vacum pipes had a small split, i had tryed new injectors and fuel pump when we noticed the slight leak. so i replaced all the vacum lines and wooossshhh! all good so put it on the dyno and we made 119 rear wheel bhp!!! very happy!!!..

thx for the help..
