Logging MAF Voltage

Is there anyway to log MAF voltage with TunerPRO? I'd like to be able to create a histogram to average my BLMs at a given voltage. I could use grams/sec, but would have to change the histogram every time a MAF table changes.

Re: Logging MAF Voltage

I've created a spread sheet that should allow me to place the avg BLM for a give MAF value and then covert it to its new value. Basically (BLM1/128)*Gram/S1=Gram/S1a...(BLM2/128)*Gram/S2=Gram/S2a... and so on.

I've got the MAF voltages (from the MAF tables) labeled across the top row and frozen (always at the top) to keep me oriented to where I am.

Anyone see any issues with this method? If it works, I'll make it available for everyone.

Re: Logging MAF Voltage

I got a 15-20 minute datalog yesterday afternoon to try out my new MAF Table calculator. It seems to work pretty well so far; of course, I haven't gotten but the one session yet. I did get some inconsistancies in Table 6, but hope these will start to correct themselves the more I tune the car.

Re: Logging MAF Voltage

Got a second data log today and things seemed to be a bit more in line; so, here it is. You'll need to replace the first row of Gram/S values with your own. I should have put the info in rows instead of columns, but it's easy enough to paste it into a new file and then convert from rows to columns. Once you have it in columns, you just copy and paste into the corresponding MAF tables.
