VSS Question and more

I have an '83 305, Qjet, Edelbrock Performer intake and mild cam mated to a '91 4l60 with automatic TC lockup conversion in a 1971 Toyota Land Cruiser. I have no smog requirements.

I just bought a complete TBI system from an '87 1 ton pickup (350 engine).

I know I will need to replace the injectors and memcal pack.

I will need to delete the EGR.

I will need a memcal pack for either a manual trans or TH400.

I have a 16 pulse VSS that connects to a programmable AutoMeter speedometer. I bought this to allow me to reprogram the speedometer after tire size and gearing changes.

I assume I can get a custom programed chip to replace the stock prom to deal with the trans and EGR. My question is about the VSS and what I should do about it.

Suggestions? Will I be able to run without the VSS setting? What does it do exactly?

Thanks,

Steve

What ECM did you get?

I should have stated that. It's a 1227747. It's in the mail so I don't know the prom codes yet.

No need for VSS to that ECM unless it's going to be used for TCC lockup...

Thanks for your reply. I wondered what the VSS was used for. So if I get a manual trans prom, such as ARPC7509, then all I need to worry about it the EGR?

There's a lot of differences in an Auto to Manual bin, so you should have a Auto bin.

If you don't have EGR you need to turn it off in bin so it does not work or when it does kick on it changes fueling and spark. Not just disable the Error code.

VSS is just an error code and won't effect running.

Air pump is just an error code and won't effect running.

So a stock ARPC will be the wrong bin running with 3 error codes...

There's only one right way to do your rig and that is a custom built chip. If you want to learn this is the place, if you just want to buy one that works PM me.
