Mild build 302 tuning

Unread postby jhine5588 » Wed Dec 20, 2017 6:59 pm

I'm back with another project. Mine is on hold for the cold months here in the Northeast but my buddy and I are ready to fire his '56 pickup here in the next week or so. I figured I'd start a thread to kind of get some info out there before I run into any snags. I won't get into much details other than engine specs.

There is a lot about it that we don't know but here is what we do know:
302 base bottom end
Edelbrock E-street heads
shorty headers
aftermarket TB and EGR spacer
stock injectors
Aeromotive FPR
Pro-M mass air- I have to get the part number cause I think he bought one for 42# injectors rather than 60# like I told him per decipha's writeup

We are running an AOD with Lokar throttle cable and kickdown setup. We would like to run the fan with the computer. His AC system is stand alone from Vintage Air but has a signal going into the EEC. He used the FRP 5.0 mass air harness and we are using an A9L computer.

I will be starting with the A9L2 base calibration to get it running/mobile before it goes off to the paint shop. I will keep you all posted with any issues and progress that might happen.

Y'all shouldn't have to many problems with it. The injectors will be close but I'm sure you already know that. Make sure you get the kickdown right because it will trash the trans if it's not.

I figured the injectors would be close provided it isn't stroked and the cam isn't ridiculous. No idea what either are however... Guess we will find out!

We ran into a bit of a snag. The previous owner never locked the converter into the pump and we didn't find that out till we were trying to bar the engine over to get #1 TDC!! That is repaired and we will be attempting the first start tomorrow morning. Fingers crossed it goes well!

kick up the base pressure to 85 psi and dial it in

otherwise set the limiter to 3k

Decipha, are you recommending to keep the fuel pressure at 85 for the sake of the injectors?

It is a PRO-M 80 mass air. Are their numbers pretty accurate? BTW, it appears to be for 42# injectors if I'm looking at this correct... I attached a picture of the sheet.

If I'm thinking about this correctly I can multiply the stock MAF transfer by 45% (19/42=.45) to get the 42# calibrated meter back down to match the 19# injectors...

This is my first time having to do this and don't want the truck to not start due to an air/fuel issue. Thanks!

yes the injectors are entirely too small, anytime u put aftermarket heads on a 302 you need 30 lb injectors MINIMUM

pro-m flow sheets are usually pretty close

no such thing as matching maf to injectors when you are tuning, but your math is correct for the actual maf curve for that meter

it takes a huge fuel error for a vehicle to not start so no worries

Ok, thanks for the heads-up on the injector sizing.

Come to find out they didn't fix the binding issue on the converter. I had to pull the trans back out yesterday to unstick the converter and break the bad news that he needs to buy a new one. Hopefully be back at it this week.
