Re: Spark Plugs with Two-Step
Off subject but where do you get a less than 3000rpm 2 step chip? TIA

Re: Spark Plugs with Two-Step
With the EFI systems, you just type in any RPM you want and it takes care of the rest. I'm not sure who sells chips that go down to 3000. Don't have anything that low in the super stocker that's for sure!

Re: Spark Plugs with Two-Step
MSD makes an adjustable module which goes down below 2000 - plugs in like chip - I have mine set at 2800 for launch.

Re: Spark Plugs with Two-Step
The low RPM chip that MSD sells is red, and it comes with a small slot blade screwdriver that is used for adjusting the limiter RPM screw located on the side of the chip.

Re: Spark Plugs with Two-Step
Bobby, I use the 8670 MSD adjustable RPM module. Has a lead that plugs into my MSD box where the chip would plug in. Goes down to 3000 RPM, turn the knob to select RPM, in 200 RPM steps.

Re: Spark Plugs with Two-Step
Biondo sells a push button below 3000 setup. Nice. Used it for years.

Re: Spark Plugs with Two-Step
I did not see any mention of open or closed loop. Maybe if stayed in open loop on 2-step, could keep from adding unwanted fuel, and then go to closed loop very soon after releasing brake. You would have to be close on your fuel map. Also, you might consider talking to the tech line guys at NGK. I have found them easy to get a hold of, and very knowledgable. I have always been impressed with the quality of NGK plugs.

I have had to replace so many new NGK spark plugs to cure misfires in customer's vehicles on my dyno, when my shop was still open, that I won't use them. I have had fewer problems with Autolite spark plugs than any others.

Re: Spark Plugs with Two-Step
FAST goes into open loop automatically whenever the two-step is activated. I have closed loop pretty much turned off at high rpm high load. I only use it around the pits to keep the plugs clean.
What are your thoughts on irridium vs platinum vs copper? |
