Hi new here . What is the best way to fix my KB supercharger after the optimizer dies. Ive talked to KB they said I was pretty much on my own and to check some forums because some guys were using different things to get them working. I have a 99 shelby durango with a 5.9 .When the blower worked it was great the truck feels like a snail now. The optimizer fried my factory computer and the harness to connect them. No luck finding new parts and I dont want to hook the optimizer back up if its going to do the same thing so what are my options??

as far as i know the optimiser just ads fuel and pulls timming. so just switch over to a fmu style setup and ruyn a msd btm unit to pull timming with boost
Who did you get to install the smt6 ? Is there someone in PA that installs perfect power equip.? I have seen the name Bob Ida so I checked his web site . How much does this set up cost to get installed and programmed?BradleyGT said:
Thanks again

NO, FTC-1 with 42lb.hr injectors that I need to get rid of now.

KB w/o Optimizer
I went to Bob & Ida Automotive. He got it working, but it was by no means well tuned. Bob is a very nice guy and knows alot, but there were things missing the tune when I left there. WOT was awesome, but everything in between was almost undriveable. You never knew what you were going to get at part throttle. To quote Bob, "it's not going to be perfect everywhere now....it's a hot rod now". I have since added lambda tuning, and worked on the fuel maps to a very easy to drive, smooth, powerful, consistent tune.
I installed the SMT6 myself. I just went to Bob to program it and test it on the DYNO. It was around $500 or $600.
What Bob didn't do:
1. we (5.2/5.9 KB) need a voltabe clamp on the stock MAP sensor...set at no more that 4.39 Volts. Bob had that voltage set a little too high for my truck. I discovered the voltage limit by trial and error. If MAP voltage gets too high on the way to the stock ECM, it will shut down the fuel.
2. Tuning Lambda is quite useful. The ECM will run closed loop in up to 4-5 lbs. of boost quite often. So, the ECM is trying to dictate 14.7 A/F even under 4-5 lbs. of boost. I've set up the analog map on the SMT6 to dictate a smooth transition from 14.7 to 12 or so A/F on the way to boost. So that in all boost situations, we're getting plenty of fuel. The key here was getting the SMT6's injection fuel map close enough to where the ECM has to make very minor changes to maintain the desired A/F that is being dynamically controlled by the SMT6's analog map.
If you choose to go to Bob, I'd be happy to forward my SMT6 maps to him for use on your truck. There should be discussion between him, you, and me before that could happen though.

The MAP issues was why I went with the FTC-1 it has a built in 2.5 bar map sensor and has data aqusition so I can take a recording and look at at it later. Also I didn't have to run auxilary injectors cause it can handle up to #60 primaries without idle and part throttle issues.It also allowed me to set timing retard for boost and I can wire my wideband into it and view the parameters on my laptop.
