Default MSPNP faq

Thanks for the faq guys, I should be ordering in the next couple days. I just have one question (and if it's in the manual, I apologize).

FS - you give a rundown of the process for adding it to an n/a car and then turboing, but what about most of us who are trying to add the PNP to an already FI car? What's the order then? I would presume it would be something like; install PNP, load base map; if working, delete AFM; then the big injectors (remove FPR @ same time), then WB02, etc.

Can you spell out the process?

Yeah I think you get the point; make one change at a time. This is what I'd rec for you:
Install WB
Install MS, basic install only, make sure it works
Remove AFM, make sure everything's still ok
Remove FMU
Swap injectors
Tune

Awesome, installing WB02 first does make more sense.

I did it all at once. Installed the PnP, bigger injectors, turbo, and deleted the AFM. The car fired right up. I had to tune the idle in a bit, but it did fire on the first try.

Exactly.... Andrew's setup (Savington) came together really fast, he's got skillz. I was impressed at how quickly he made all the changes he made to his car and kept it all together. Unfortunately many people stumble when they try this, and like Ben said, if you do have a problem along the way, you won't find out until it's all back together and then it's hard to put a finger on exactly what it is.

For instance-- I had another MSPNP beta tester that did much the same thing, MSPNP, turbo, injectors, BOV and Boost gauge, all at the same time. Emailed me and his car was idling at 2000rpm. I looked at the logs and could see the MSPNP doing everything it could to bring the idle down, and where it had the idle valve DC at it should have had the idle in control, but it was still at 2000rpm. I told him to start looking for vacuum leaks. After a long search he came up dry. I told him it had to be a vacuum leak, try again. Then finally he found one at his boost gauge. Idle came down to 1700-1800rpm. That wasn't the only problem. I asked him how he changed his injectors, he hadn't done it before and hadn't taken apart everything needed to have adequate clearance and I was concerned he pinched a seal. I had him try and rotate the injectors and two of them wouldn't rotate freely. That's a problem. He pulled them out and one of the o-rings was mincemeat. He replaced these and problem solved. Had he done these mods one at a time he would have known the MSPNP was working properly before he attacked anything else, then we would have known when he added the boost gauge that he must have introduced a vacuum leak because his idle jumped 200 rpm. Then he would have really known something was wrong when he put in the injectors. Each time he would have known exactly where to look for the problem. Instead I spent ALOT of time on the phone troubleshooting issues that really weren't my own. I'm glad I was able to help, but there's a better way to do this for everyone. Particularly for the customer who could have avoided significant downtime.

To answer your original question Kotomile-- this looks like a good approach to me, and I'll expand a bit and get it added to the FAQ, it's a work in progress. Up front the only thing I'd add is that after each step and before the next, make sure all is well and working as expected. If not then fix any issues before moving on.

Right, otherwise what's the point of doing it one thing at a time if you don't test?
