Where I am at so far.. - ZR-1 Net Registry Forums

Wanted to give you a brief update on where I am at with everything;

There are 14 outputs on the haltech p2000, so here is how I am going to wire everything;

I am going to run the first 8 injectors in sequential (eight outputs)
I am going to utilize a resistor box, and run the second set of 8 injectors in batch.(two outputs)
Obviously I am going to run wasted spark on the 6.0 truck coils (four outputs)

There is no way I can make the haltech read the factory crank sensor, so I am going to modify a 60-2 tooth wheel to fit the harmonic balancer, and fabricate a mount for a bmw crank sensor. I ordered two of the wheels, and am going to try to place it on the backside of the balancer first, and if that fails I will simply bolt it to the front of the balancer.

Along with the p2000 I purchased the wideband setup that will direct p&p into the haltech. Once I get my base tables set, and a target afr, the haltech will take the readings from the 02's and adjust the afr in real time (temporarily, unless I set it to modify the base map permanently). I also purchased two new ait sensors (screw in) so that I do not have to worry about them blowing out under positive pressure, and both the stock ecu, and the haltech have a reading.

I am going to retain the stock ecu for all on essential functions (guages, a/c, etc) and just start by robbing it of the inector and coil control. I am not too sure how "smart" the old factory unit is, but with any luck it will not recognize that it is no longer firing the coils, and injectors.

Preliminary work has begun, and I am waiting for further parts at this time.

Fuel;

I am going to modify the stock hanger to become a true "twin feed". I am going to utilize the stock fuel line as a feed, and run a new -6 an ss line for the other. Each rail will have its own independent feed line, returning to a "y block, to a aeromotive afpr then back through the stock return line. It should be noted that the standalone I purchased has the "long leads" which includes new fuel control (triggering fuel pumps) with relays. I opted to go this route instead of allowing the factory ecu to continue controlling it. It just makes sense to take this function away from the aging unit for reliability's sake.

Brand new 63# seimens injectors for both primary and secondary injectors will supply the fuel to the engine. Entire secondary system (minus injectors of course) will be removed, as well as ignition module, coils, etc.

I would also like to say thanks to Jerry (took pictures of the crank for me), Pete, the Haltech guys for their great customer service, and everyone else who have helped me by answering my constant questions.

I am now a Haltech dealer, and my total cost in the project is as follows;

Standalone $1650.00
COP'S-$53.51 x 8
Wideband-(with two sensors) $290.00
crank sensor-$60.00
Boost controller-$60.00
Resistor box-?
