There's not a 'guage' specific for timing. But, you can log the spark advance. I think the short name is just 'ADV'.
There's no such thing as base timing. 12deg is just the advance the ecu uses when you manually set the sync between the crank and distributor. Timing advance is always referenced to TDC.
I'm out of built up cables. But I have parts to build several more. Just haven't got back around to it yet.
Okay thanks, I have one already but wanted to purchase one more.
Thanks for helping me out here Rob its super appreciated, I hve more questions for you tho ! LOL ! I mean I got the ECU programming guru answering me !!
I noticed in the gauge tab there is two greyed out options one for AFR and one for Wideband. Is there any way that I can have these made available as I would like to monitor my Wideband ---- what an awesome program!
Thanks
Nick
the afr option was an attempt at one time to calculate the afr ratio based off of the injector pulsewidth and map readings. i could never get it to give a reliable number. the wideband was a "wish list" item where i was going to incorporate the ability to read a 3rd party wideband data stream and read it into an mpscan gauge. i had planned on using my lc1 but ended up putting it in my camaro instead so never did anything more with it. i did get a ngk that i'm going to switch out with the lc1 so maybe in the future i'll revisit this.
a very workable alternative is to use the wideband in place of your narrowband which would allow you to read the afr. rob and others could help you set that up. do a search. there have been some very recent posts on individuals using that option.

^ this. I just went through getting my AEM setup and it works like a charm. The only thing I'll say is that the gauge in MPSCAN may not show exactly what the WB gauge shows due to the gauge display rate ( and that can be changed in MPSCAN ) . In my experience the WB gauge itself is faster. I haven't been bothered by it enough to try and fiddle with it.
Thanks for the reply's so I have decided that the best route for the time being is to keep the narrow band and use it along side with the wide band and if they are both consistent with each other I will delete the narrow band all together and run the analog signal from the wideband to the ecu.
I will be putting mpscan to work next weekend most likely and I will give you all an update.
if you want the fastest response rate limit your gauges to the basics, eg. afr, rpm, tps, map and set the logging rate to something like 2 ms. mpscan will basically log as fast as it can and those 4 gauges can be used nicely in mptune to work on your peftbl. just remember that the log file size will grow rapidly so you probably only want to use that rate when doing some WOT runs and then saving the log file after each. for general use i'ld leave it at around 100 to 250 ms. the display rate and logging rate are run on 2 separate threads so a slower display rate shouldn't affect the logging rate much.
