My question pertains to running the IQ3 Street dash with a pre 2008 Ls1 ecu such as the 411. I have a N/a 408 Lq4 EFI *high compression race engine with Vacuum pump that makes over 750 at the flywheel for my chevy S-10 truck with a 4l80e trans. I called the company yesterday which was Friday. I was told that the tach and speed signals may be slow to register. The young man stated that there was a MSD part that would help. I asked if he could send me a Email with the parts needed to help make this a non factor along with everything needed for the IQ3 including the dash itself. I'm not a computer wiz as my electrical guy will be doing the wiring and trying to keep this as simple as possible. I just wanna know what all do I need to not have any problems.


Thanks!
