I just wanted to see who out there is running a UTEC with alcohol/water injection. I just began to seriously tune my evo with it and I am up to 29 degrees of timing and ~28psi with zero knock, car pulls like mad. So far its trapping 114.69 from a roll out. I have my AFR's around 11.6. I was attempting to tune the car using the progressive controller but I just couldn't figure it out, I ended up setting the controller to spray full blast at 2 psi and it turned out much easier to tune. It was like tuning for c16.

What nozzle size and pump pressure are you running? I am suprise that it didn't knock at 29 degree and 28psi! It is a lot of timing for EVO. You must have spraying tons of alky...

I have a conservative tune and it is now running at around 21deg at 7000rpm tapered to 22psi (25 psi before 6000rpm). I can be wrong, but 29degree is very well above the range that create maximum torque. Over advancing timing will tend to give you better fuel economy instead, but not neccessary best power. Seeing that you have upgraded your ignition too, I think you really don't need that much of timing advance. Unless you were running overly rich, which lead to a faster burn and it will change your timing advance requirement.

Start spraying alky at 2psi might make it spraying too often. You really don;t need alky during light load. FYI, I've replied to one of your post here about tuning alky with UTEC:

I am using a 375 ml/min with a 150 psi pump at full blast. On my pump gas map I have timing at around 20.5. Yea The 28 psi is only a spike, it drops as it gets near redline. My afrs are 11.6-11.7 at WOT. Yea I saw your other post, I haven't had a chance yet to try and tune the car that way but maybe this weekend I can give it a try.

 

Im using a SMC kit with the M10 jet. Works great and run about 22-23 degrees of timing at 26psi. The tune would be a lot better if I can get my hands on a non-leaking BOV

 

2psi spray is too early

 

I basically just wanted to run the car as if it was on race gas, yea I go through a lot of meth, but until I figure out how to tune the car for the progressive controller I am going to run it like this.

FWIW, I have SMC M7 jet running at around 125psi alky pressure. I had good success with starting spraying at 12psi, but i am now trying 7psi so I can bump up the timing at earlier and see if it makes more torque.

 

bump for a lot of useful info...

 

utec and meth is sweet cause I can switch maps from drivers seat and turn on and off the meth when I want on the go. Stock turbo + meth = 375hp 385tq

 

holy crap that is amazing!! lol i want that power.. how much psi?

 

This was great when you couldn't switch on the fly your ecuflash but you can now do so.

 

i hit 28psi taper down to 23-24 tuned by jsrmaine at turboxs. going back this weekend for green tune

 

what do you mean... dont you still need a laptop in car when switching maps on stock ecu??
..im trying not to buy a laptop lol

 

No there is an optional map switch for the UTEC.
