Hello guys, here is what I have.

First I had tec3r and i been using the software 3.5.6.. the car was having issues where after 560whp or so the car started to buck and fuel was maxed out. So my buddy who is a electromotive dealter could not figure it out for a while, I kept messing with the tec3 and changed the setting from 2amp to 4 amps. Automatically the car just started running real rich and now i was able to make 700+ whp with fuel still available.

my setup is 4cyl
1600cc injectors (5.7ohm) I just got this information from the shop guy that ohm out the injectors.

I am going to convert now to e85 I will be running 4 primary injectors and 4 secondary injectors. I been reading a few post and now I am scared because as waht John says that you should not run low imp injectors in a single chanel... But my car is full sequential, or that is how it was installed. I am just scared that something is going to happen and the injectors are not going to open..

I already know how I am going to do my stage injector setup.. I am going to tune my primary until I reach about 80%dc. then i am going to tune the VE in primary to show 80%duty cycle all the way to the top and then I am going to start tuning the staged injectors from where there...

Please can someone give me some input on this. I am going for 800+ and I do not want my engine to go bad because an injector issue.




thank You,

Edgard

I had the same issue. I spoke with Uwe and we agreed that since I have 160 lb/hr. bosch injectors which aren't really a low impedance injector nor a high, that I might be better off using the 4 amp setting. My dealer disagreed also and as I had already blown a head gasket, bent a wrist pin, and destroyed a piston, what could it hurt? The improvement was amazing, with similar results to what you describe, with managable A/F and egt's on methanol at about 975 deg. I personally don't think the injector was able to fully open with the two amp setting, even though the tec showed reasonable pw's.

hey thanks for the reply.. I guess you and I are 2 of a kind lol.. I really hope this cuases no issues no my setup... What is the max duty cycle that you are running ?

Changing the setting required me to redo all of the fuel tables, I'm just about done with the primaries and am at 83%. time to turn up the boost and work on the secondaries.
