Base map for 1.8 swap
I'm about to swap a 94 1.8 into my 91, and I'm not sure whether I should start with a 1.6 base map, or a 1.8 base map. Does it even matter? Here are some details:
1991 car/harness DIYPNP 90-93 ECU Wired for sequential injection Retained the 1.8 TB with oem VTPS coils rewired for 1.8 1.6 thermo sesors retained AFM deleted Flowforce 610 injectors |
You'd want a basemap for your 91.
Change required fuel to compensate for your 1.8 and larger injectors, the mod for the VTPS should be in the MS hardware, and tell it you have sequential injection. The MS is only sending out a ground signal for the coils, so it doesn't care what coils are using that signal. 90-00 (even 01-05) coils are close enough to each other to use the same dwell even. |
Wouldn't it be better to get the VE/fuel/ignition tables from a 1.8 basemap? Or are they the same?
|
They're roughly the same VE, so yes same fuel table.

Thanks Curly. I'll see if I can get this puppy up and running. I'm pretty new to MS tuning.
