Why would I care if DSMLink knew about my GM-MAFT?

[ChiGGz]

I never understood why I would let DSMLink know that I'm running a GM MAF. The MAFT converts voltage to Hz so I don't understand why the extra step?

of course you got the gm maf because it is a better metering device than the factory mas. it would make sense to zero the gm maf for stock and do all your tuning and logging inside dsmlink. tune it in one place instead of two. plus you can better see if you tune is correct based on actual a/f (gm maf) as opposed to what is estimated inside the ecu.

So what your saying is that I can link dsmlink directly to my GM MAFT? and measure air through that? In effect getting an A/F ratio?

sorry, still alittle early. i meant to say airflow reading not a/f ratio.

when did you have to tell DSM link you had the translator? When purchasing? I just went to the website they did not have a option or drop down window for "translator equiped" vehicles?

For troubleshooting? IE posting the link forums? well thats a givin, concidering if you did not properly zero the translator. V2.xx does not use 0 on the aux knob for stock injectors (they use 4 on 2g's, with the base being 0 on both counts). Plus they would probally check to see that you have checked the "clamp IAT and baro" box under misc.

In terms of setting up DSMLink I was under the impression that there was a drop box in the program asking if your using a GM MAF.

Good thing you mentioned about zeroing the injectors though, I automatically assumed 0 meant 450cc : |

 

[spoolup]

it does but only on 1G not the 2Gs.

for a gm maf on either one would require a tie in to a 'not used feed' to the ecu. if you unhook the factory mas (barometer)...tie in the gm maf in its place, then rename it to show the gm maf. zero out the gm maf as if you were running 450cc injectors and then tune and log using the dsmlink. as stated, it is all covered in the users group.
