I have a 1969 Oldsmobile F-85 that will be fuel injected (hopefully) this spring
Drive train
- 455 0.30 over to 468
- 750 Holley with milled choke tower
- Holley single-plane intake
- A to mild comp cam
- Lightly ported C-Heads
- Hooker comp headers
- 2.5" Flowmaster exhaust
- Th-350 automatic with manual valve body and 11” converter
- 12 bolt rear axle with 3.92 posi
- Recurved GM Hei
Chassis
Front
- 12" disk brakes
- Tubular A-arms
- Fast ratio steering box
- Polygraphite bushings
- 1 3/4" sway bar
- Custom wound coil springs
- Koni adjustable shocks
Rear
- Stock drum brakes
- Boxed trailing arms
- 1" sway bar
- Custom wound coil springs
- Koni adjustable shocks
- Airbag in right coil spring
Plans
- I plan on converting her in steps.
- Start with modifying the intake to accept injectors (think 36 lb/h will be right)
- I will then use the carburetor as a throttle body in the beginning, just modify it to have a TPS
- Something like this guy has done but I intend to leave the carb unmolested.

- I don't think there will be any problems other than the fact that I have no IAC, this is only a temporary step, and if the fuel injection works properly I will get a good throttle body from the US containing TPS and IAC. (I will also use the Hei to run the ignition)
- Installing a new throttle body.
- Converting the ignition to CNP and ditching the Hei.
Thoughts
As a crank trigger I plan to use the hall that is in the web shop, I plan to make a trigger wheel out of aluminum and press in four magnets with 90 degrees between them, this will then be mounted on the vibration damper. The hall sender will then be placed in an aluminum adjustable holder.
As cam trigger I am still considering whether to mount a magnet in the timing chain gear or modify the distributor.

Question:
A friend of mine want to buy a 3.2, I dont have the time to help him with the soldering so he is probably going to buy an assembled 3.2. Do the assembled controller include knock sensor interface, egt sensor interface, ibutton interface and dpack fet's or do i have to solder these inn place for him?
TJP
I se that there is a new batch of GenBoard in production now, v3.2. Check GenBoard/VerThree
Will there be changes on the web shop regarding what you can buy and the quantities? NO
Can I go ahead and order right now? YES
(given that ver 3.2 will have FETs and other components installed)? NO, the sub200 Euro board will only have max 2 DPAK FETs auto-soldered; 18 switches are still TO220, ordered as different item and everyone solders their own except the 450 Euro assembled unit.
If I choose to use lowZ injectors will be able to do that or do I have to modify the board? v3.2 supports PWMing out of the box, 4 FETdrivers (for 8 FETs).
I intend to use PWMing.
8 diodes are already mounted on v3.2, just need to mount 8 diodes or shorts, very easy. Check GenBoard/Manual/DDFlyback again...
Hmm
I have v3.1 so i gues that i have to mount the diodes
(D7, D8, D10, D16, D17, D25, D28, D29 and R19, R20, R37, R38, R61, R62, R93, R94)
and resistors
(R18, R21, R36, R39, R60, R63, R92, R95)
myself, but thank you for the explanation. think i understand now.
