nitrous help

[5.7ute]

Ok thanks for taking time to help. What should I work on first with the na mass? I thought it was pretty good but shows what i know... any advice?

IMO the first thing to do is get your wideband logging into Efilive. If you have the V2 unit the best way is to get a serial cable from TAquickness. If you have the V1 you will need to go from the EXT.ADx analog ports with the supplied cable(if they ship one with the lm-2). Once this is done you will need to ensure that your IFR table is correct for your injectors & rail pressure & then go through the AutoVE & Automaf procedures.
Fuel supply definately seems to be a problem so you will need to check that out as well. Logging fuel pressure is a good way but it costs a few dollars to set up.

V1 or V2 is the flashcan device. V7.xx is the software. If you have a look at the heading on this forum V1 is the one on the left. V2 on the right.

Ok I think I have found out what the problem is. I took the fuel solenoid apart and cleaned it. I then with the car off and nitrous off hit wot. the fuel sprayed out like crazy, before I cleaned it it wouldnt spray much at all. Now I run a 12.4 with the .033 back in. So now I'm going to ordr a fuel filter and try again. Thanks for all the help!

you moved your nozzle AFTER the MAF now right?

I still cant believe you are spraying a wet shot before the MAF... You should get the Nirto Daves plate, its a nice piece.

I agree. At a minimum I would ensure that the timing is pulled right up to the 1.2g/cyl limit. In that log you posted you can see the first hit of the gas run up to 28deg advance. Luckily the P0103 code set before the second hit or damage could have been done to the engine.

I'm no expert, but I agree with what 5.7ute and waterbug1999 have said.

Log DYNAIR and DYNCYLAIR; get rid of some other pids (get channel count to 24 or less).

HO2Sx1 voltages indicate you're lean (altho do not rely on those, get a wideband or two).

If you have a wet plate before the MAF, then the MAF getting wet will cause it to misread.
