89 TPI swap into a 77 vette-issues
We finally got this swap up and running, and run into a few issues.

Here is a littel background info

1977 Vette
5.7L 350
Manual tranny
89 TPI intake componenets/distributor
S10wildslide engine harness
Moates adapter in ecu

When running the car with the APYU bin, after removing the vats and setting it for a manual tranny, the car is non-responsive and I get a cel code 33...MAF sensor voltage too high

I have ran a BIN called 89vets...which did not give me the MAF cel code 33 reading, but still is not responsive

Anyone have suggestions on what map I should use to get this car running somewhat correctly with just a basemap???

The only roms I have been able to ID as being compatible thus far are APYU, APYP, and AUTM. Anyone know of more, or the precise once I should be running??

Is the CALPAK from a 350? Backup Mode may not be ideal for the setup if the donor CALPAK does not have the 350 TPI data. Is the system reaching closed loop?

There are many bin files that will run your setup. ARAP seems to be a pretty good base.

I got some help from s10wildside, and a spare MAF sensor. All is well, get an intermitent EST code, and a VSS since we have none hooked up

All seems to be well

Have you ensured all the basics are correct? Timing, fuel pressure, etc?

I have tried an arap bin with little luck. All seems to be working well now, except for a VSS sensor issue (using a mechnical VSS, so no drive for the ecu at this point).

On this note, does anyone happen to know if a sensor is made to allow both cable drive, and electrical output from the vss sensor, possible an entire replacement sensor??
