Wait - elaborate on your Haltech setup. I would never do this to a CSL but dealing with D-jet issues now has me intrigued. If you eliminated the cold start injector, have you removed all the other D-jet related components? Do you have/use some type of MPS to feedback into the Haltech? What are you using for the TPS? Did you replace the entire harness? If so, that explains the absence of the other black majic D-jet parts...
With a complete engine rebuild, and back to factory hp, it was decided not to put back the old ECU that was troublesome and 50 years old. So a new Haltech ECU was swapped for the D-jet ECU and yes a new harness was also installed. The Haltech is mapped to the engine, and I get faultless starting, and drives well (and 205 hp on Dyno).
That's fine if you wouldn't do it on a CSL (I bought my car with this Haltech upgrade so didn't have a choice anyway). However if I ever sell my car the new custodian can reinstall the old D-jet arrangement.
It's a bit of an expensive upgrade but well worth it to me, and my ECU is future proofed for 20-30 years before it maybe needs a software upgrade or replacement unit.
I believe there a lots of posts about upgrading ECU's, and other good options are recommended such as MegaSquirt.
