SC and injector install car idles at 1700
Car before 90-93 mspnp with 97 1.8 engine swamp - only thing 97 about the car was the engine - rest of the electronics are all 91
Things that have changed from the install from tan top 254cc to 305cc supra injector fuel pressure set at 60 psi 94-97 - IAC removed TBS I went in and changed the REQ FUEL to 1800cc and 305cc I changed the PW - subtracted 1.3 from all the values and the car idled a bit lower but still high at 1700 rpm and the AF was about 12.6 I am wondering if my next step is to change the PWM - 2 wire setting http://www.showyourmedia.com/files/1267248071.jpg to correct for the new 94-97 IAC |
Yes, use the '94-'97 IAC settings in this case.

With the 91's dashpot settings since he didn't bring over the 1.8 tps ;)
Maybe try the 91's minimum duty cycle as well. |
lol..............the car doesn't fire up now when it is warm............. around 60F
I tried adjusting after start settings, I got it to start up but had backfire from being too rich and then it dies out. After reading a bit -there are 2 things i can play with after start enrichment, crank timing from 18 to 12, and |
Please read the tuning article I linked you to in your other thread. It will help you immensely.

Tried today no luck, will get a new game plan and go try again tomorrow. My car started before with 254 injectors, the last ditch game plan is to put my old injectors back in and go from there. The best i got it was to start a little and die (car runs rich) and with backfire. T
The car also started up before, but now it doesn't start up anymore. Wonder if the IAC has anything to do with this. REQ_FUEL is done, subtract 1.3 from PW calculator, cut ASE and Warm-up by 40% since injectors are about 20% larger and the stock FPR is at 50psi, but now I am feeding it 60psi. These are the old setting for 254 injectors that ran just fine http://www.showyourmedia.com/files/1267502737.jpg and from the ms1 extra tuning instruction # If the engine tries to start, but dies right away, you need to adjust the after start enrichment. Generally this should be between 20-30% for 100 to 250 cycles. # If the engine starts but dies after a several seconds or minutes, then you need to adjust your warm-up enrichment. |
