#51794, "I give up. SERIOUS tuning NEEDED"


          

I have a 95 ESI A/T. I think the main problem is I have adjustable things that I really don't know how to adjust. Here is the complete list of engine upgrades: Short ram intake, P&P TB, OBX adjustable FPR, Injectors out of an old Thunderbird 2.3L T3 Turbo coupe, Crower Stage 1 Cams, Fidanza Cam Gears, Greddy Cat-Back, Hollowed Cat, MSD Digital DIS-2, coil pack, and wires, Bosch Platinum +4's. My tranny was rebuilt with high energy clutches, updated low/reverse piston, updated snp ring kit, updated solenoid block but a dayco 1900 stall converter was put in. Now for the problems: I run 18.7 @ 86 mph, When it was stock I ran 18.5. When I am at a stop light the engine will die if I just restart it will run ruff and have a 4000 rpm rev-limit I have to put it in park turn the key all the way off and then restart. This especially happens when my A/C is on, This started happening when I put the cams in. Also I have no low end power. I have put a lot of money into this thing and still its slower than my friends ford aspire off the line. Any idea how I should adjust my cam gears, FPR ,and MSD. I have no clue how many cc my injectors are.

This isn't advanced.

None of your mods warrant any injector over stock, nor any fuel tunability supplied by the fuel pressure regulator. Also, installing an unknown injector size is generaly a BAD idea.. because then you have no idea what to tune for. Ditch the injectors you're running, install the stockers, and adjust your base fuel pressure to stock levels (~50psi static, 40ish at full vacuum), and try again. I guarantee you'll run better.

And what do you think about the cam gears , adv/ret? a mix? how much in each direction or should i just fool around with it? Do you know where I can find a 97 ECU pin out?

I think it's +2 on the intake, and leave the exhaust on 0 for the best gains.
Am I right guys??

I'm going to put the stock injectors back in until I put the turbo on. According to Corbins equations and my est. HP I need to run my stock 235 cc injectors between 32-34 psi at idle. Anyone else have any ideas? Also, with my cams I have had them at +2/0 for idling purposes and I notice more low end power but for racing I change the config to +2/-2 and this gives me a nice top end increase but decreases the low end power. I can say I have learned alot from this board and have found this one the most useful. Thanks u guys! anyone else have any suggestions?

Don't run that low of a fuel pressure, unless your fuel trims warrant it. If you don't have a datalogger to confirm those fuel trims, keep the fuel pressure at 47psi.
