69 mfi adjustment
I am working on a 69 911e motor and would like to make it a bit more driveable. Let me say that the motor runs strong like a race car. For the past 5 years I have used it only 2 or three times a year. To go to FCA race events, never had a problem on the track, but now I would like to drive it more often. I would like it to make it more street-able, user friendly and still run strong. I have been working on this motor for over 10 years and never played with the fuel injection because that is what the hayes manual says.
Here is a list of the motor upgrades:
K&n filter
Bosh distributor with optical pick up
Bosh coil
Crane cams optical ignition
Perma Tune hid unit
Firebraid wires
S type Platinum plugs
Sebring exhaust
I recently came across the tech info for the injection and am not sure what to do. From what I’ve read, these things don’t need any normal adjustment and if there is an issue it is most likley not the injection. So, check everything else first and then double check. I have done that and it runs great but it back fires every time I let off the gass, the fuel pump has a gremilin, a cylinder looks to be running a little ritch, is hard to start when warm, heats up in trafic, never runs good cold. It will drive and idle fine even when cold but I need to keep the revs above 3500 to go any where.
The cold running looks easy to fix by getting new thermostat hoses, I have never had them on. Will this affect my over all performance? Is it running rich all of the time? Will that hurt the car? It runs good and I don’t want to mess with a good thing.
The warm start issue is confusing. I don’t have the thermostat hooked up so why is it hard to start. I think if I make a dash switch for the enrichment solonoid? The one that pumps gas in to the air cleener. That should fix it. Squirt some gas and it fires right up.
any sujections would be great.
