Im looking for Help making Old Glory run Better! I have a 57 chevy Trike that i would like to put TPI in the half moon two barrel carb sucks in a bad way and hesatates top end. This trike is used in local vetren events and Toys for tots and reflects The pride of America. If there are any car guys out there with a computer and wireing harness that would work please contac me on facebook at

I have raised most of the parts needed to install just short the wireing and computer thank for reading this post Tim

 

For a TPI set up there are both MAF and MAP based systems. MAF being mass air flow and MAP being speed density (SD). On the '85-'88 MAF systems they used a cold start injector. In '89+ this was eliminated. So if the TPI set up you have does not have a cold start injector then a '89 - '92 system must be used.

MAF was '85 - '89, with SD being '90 - '92.

Three different ECMs were used. '85 was a one year only ECM and is best to be avoided. '86 - '89 used the '7165 ECM and was MAF based.

'90 - '92 used the '7730 ECM and is SD based.

The wiring harnesses between the MAF & SD systems have major differences. So check the TPI for a cold start injector first. If none, then need to go '89 + on the harness/ECM.

Then decide whether you want to plumb a MAF into the air stream. And decide on that or a SD system.

I could use some help making sure each fitting and hose conection is in place right
This is not driven in the winter so i don't think i need the two small hoses behind the throttle plate for de-iceing and i guess the heater hoses must flow coolant thru the upper plenum? Please look at my drawings and if its not right please post corections Thanks

 

Looks good. Yes, you can use the provision for a 9th injector to attach a fuel pressure gauge. No, don't worry about de-icing the throttle body (most of us bypass this anyway).

Just FYI...in the first pic "Sensor for cooling fan?" is originally filled with a temperature sending unit for the temp gauge in the dash, but I am sure you could put a switch in there to activate the fans if that is your goal.
