    411 into Chev 1989 K1500 questions.

    Hi have most of the parts to run a 24X 411 on a SBC gen1 OBD1, looking for advances in ignition control with coil per cylinder. If I had done more research I may have gone a different way- but the hole is deep now;)- existing 7747 style DynamicEFI EBL Flash- pretty much a standalone, truck was converted from TBI to port TPI- batch.- 700r4- this is giving me a 411 lock up application problem.Installed EFI Connection's 24X reluctor and timing cover, have all major parts. BUT the 411 won't control older style lockup and I really don't want to spend for a 4L60E as the 700r4 has all the good parts.- leave 700r4 as is, it is well built and so far reliable.- leave 7747 as is- share TPS, MAP, VSS between 7747/411, 7747 to control converter lock up (not ideal sharing sensors, I know- a second MAP could be added)- cruise, leave with 7747- iac to 411- ac control to 411 (iac/e fans)- temp to 411- e fans to 411- tach from 411- oil pres senor to 411?- PRND trans status? Needed?- can 411 log WB O2?What's your thoughts?

    ^^ Suggested this to him on another site.My old 1983 G20 used a vacuum switch hooked to ported vacuum to lock 2nd and 3rd and a pressure switch to lock 4th.

    Does that just lockup the converter in overdrive? that kind of setup sucks compared to having control of the TCC.

    Yes it does....I personally liked the vacuum switch setup in my old 1983 G20.
