Has anyone here "borrowed" the TBI system from an Iron Duke and repurposed it to provide fuel and spark on another unrelated 4 cylinder engine? Do you prefer the distributor or the DIS ignition- assuming the "recipient" engine already has an old points dizzy? So yes, the ECU can be reprogrammed, with a laptop, chip burner, chip s and the software. The above link has good info on it, as well as other sites out there. As for vehicles, I would look for s GM 4-bangers, S10s would be a good choice along with Cavaliers and such. You can find the Niva wiring diagrams on line for free. TBI is really easy. I used a GM coil, ignition module, temp sensors, and throttle body assembly My Volvo uses a '75 B20 distributor that dropped right in to my '67 B18, which has a VR sensor that works natively with the GM 8 pin ignition module and looks bone stock. Super simple and works fine for me. Most valuable advice I'd have from a generic sense since you didn't give us much to go with is that I used a single barrel single injector TBI. Due to my own mistake when i set up the injector parameters, I was using incorrect injector duty cycle timing and failed an injector when I was a long way from home. I didn't recognize it at the time, thought my MS was toast, and had it towed home. I have fixed my MS setup and haven't had a problem since, but I definitely carry spares, and for a while I wished I had more than a single point failure

Food for thought. It appears to be clean and free to move. Find all posts by robertr

Much of this article will apply to other s era GM cars including injected big blocks and even fire V6s. The Tuned Port Injection and Throttle Body Injection versions of the small block Chevy and used very different hardware, but similar electronics. Not only do they show up in many trucks such as the C pickup, but also Camaros, Firebirds, and Corvettes, and other cars as well. Also these two injection systems are also very popular for swaps into street rods, S10 pickups, and muscle cars. For these engines, we recommend using the Megasquirt-II. It can control a HEI ignition and the stepper motor idle control found on these engines using its standard hardware. For those of you who are looking to do a less expensive installation, you can use the Megasquirt-I, but this will not have provisions for controlling the IAC.

I need to replace the injector on my '86 2. The parts dept. I've read how the MPI guys can use Ford injectors to get a boost in performance. Is there a similar mod for the TBI? Your options are pretty limited from what I have been able to find out. They are discontinued from Jeep and there doesn't seem to be a lot of options in the aftermarket either. If you have found solution options I recently used Witch Hunter Performance out of Washington state.

Could that be the pressure regulator on top. I replaced the hall effect switch and pick up coil along with the tps sensor. Rebuilt presre. Thanx again for your input.

Jumper XG1 to the right non-banded side of D5. Make sure the DIS you choose has a tach output. After more thought, so would lots of other things like a single failed wire for the ignition circuit, a coil, or fuel pump, etc. Careful consideration was made to the design of the intake manifold and exhaust gas recirculation system to ensure power output from each cylinder was equalized. I'll just leave this here lol And, you just need a large cresent wrench to take it off and know for sure. Baby steps, to be sure, but it feels more manageable this way. The elephant is a sacred animal in Thailand and you just have to take care of it until it dies. Digg del. Is this a normal occurrence, or a symptom of some other problem? I had an 84 Jeep so it had a o2 sensor in the manifold. What intake manifold did you use? I have yet to attempt a cleaning, as i thought a full replacement would be easier than disassembly and reassembly.

You can try to unscrew the IAC and clean out the port to fix this. Gasoline , E85 , LPG. You might check over at www.
