72 T3 MS3 with MS3X question

[Piledriver]

I see you run ~100 KPA at key on, and at ~80 kpa at idle, which could be bad tune, vacuum leak or lumpy cam.
Play with you dash a bit, change fuel load gauge to MAP.
(They should read ~the same on your setup, but just for sanity)

Here's my current msq, hope you find it interesting.

Just like on msextra, posting the msq and a short log showing the issue is really needed for anyone to be able to help much.
(you should zip them up together)

Pictures don't usually help much for diags, ~mostly useful for settings.

Thanks I will take a look at your msq and provide my msq to provide information to those trying to help out.

So Max is your thinking that I am see that reset also because of the 80kPa limit setting?
I had seen that setting and was wondering about it but being so new to this It did not spark the idea of it affecting the readings from the two sensors. I will try and make the change today and see if it make a difference. I remember you struggling with the strange performance issues a while back glad you were able to make progress on it.

[Max Welton]

Dunno. But if you change it to 70 the problem gets one variable simpler.

Well gave this a try but no change still not getting any reading change on the external sensor once started. Changed the limit from 80kPa to 65kPa
I do not have any screen shots but here is the .msq as it is right now.

Will try some more testing this weekend.
Might be good to see if the on board sensor will respond also. But will need to find something to pull a vacuum to test them since i dont have one of them tools yet.

[Max Welton]

A simple test might be to hook a vac hose to each sensor and suck on the end to see if the change registers back in TS.

This is my plan but I injured myself Saturday and have yet to test them. Packing to move to Texas and all the other stuff going on its putting a damper on things. Hope I can get it all ironed out before I have to take it to Texas on a trailer. Plenty of other cars to do that with right now.

[Max Welton]

Texas? Yikes! I wager you'll be having a warmer winter than I am!

BTW, hope you're OK.

Most likely and a warmer summer too

OK just limping along for a while.

Well its been a while since I have posted on my progress. Good news is that with the help of Mario (The DubShop) and Max I was able to take a drive today and actually enjoy it a bit as well as do some logging. Now I have a question what sort of things have been tried by y'all to reduce RFI noise? I am sure some of my problems are in how I ran the wiring as in hind site I should have done some twisting of the wire. So has anyone tried adding in Ferrite Cores?

As Max has pointed out to me I am getting a bit of noise in my ignition signal and I vaguely remember in the beginning of my project some one mentioning I might with how my setup is. Unfortunately I will need to stick with this setup for a while as not having a job has severely hindered the budget. If anyone else would like to look at my tune and last log let me know I will post a link to it.

Thanks to all for the input I have gotten here its been very helpful and reassuring.
