MPS Adjustment, It helps to have the right tools Options

[Mblizzard]

I post this only because I struggled to find the proper tools to adjust my MPS after going to a 2056. While I was able to make adjustments using standard tools, I could never get it exactly right. I asked several people about where I could get the right tools and could not find them. It is likely that this is well known to everyone but me, but I finally found what I needed at Tangerine Racing.

It is such a simple tool but without it you can't really be sure you are adjusting only one of the screws without changing the other one. So once again Chris is the man that can put the right tool in your hand. I have been close on the adjustment many times only to mess it up trying one more small change.

If you are playing with your MPS just get one of the MPS tuning kits from Chris it will make your life much easier.

Can someone outline the steps to adjust the MPS using a dyno and an exhaust gas analyzer?

In my area there are several shops that have a dyno and can measure AFR (air-fuel-ratio).

Can I just record the AFR under full load, turn the engine off and make an adjustment.
Then, repeat until the full load AFR is at the correct value?

I thought it was that simple but it is a little more complex. Read this 1000 times and you will get the hang of it. Well maybe you don't have to understand every word but you do need a solid understanding of the way the inner and outer screws work together so that you know what to change. Focus on understand what each screw does first then read the adjustment section.
