Dsmlink V3 with stock MAF

[Legit6MT]

I just bought a 97 GST converted to GSX. Car came with a good amount of mods.

Holset HX35 turbo
Rebuilt 6bolt motor
Blitz bov
HKS 40mm wastegate
DNP Manifold
Big front mount
Hallman Boost Controller
AEM Wideband
DSMLink V3

The car has a unsteady idle, like it will idle at 900 which is what target idle in DSMlink is and all of a sudden fall to 800 and jump to 950 and back to 900 etc.

What are the maf settings for a stock 2g maf with dsmlink v3. Any help is appreciated. Also the wideband readout is .5 higher in dsmlink than the gauge.

can someone help out?

The way I fixed my idle was pull the bottom honeycomb out of the MAF and adjust the BISS. Not sure what the setting are in DSMLINK

Typically 0% across the board, but it will need to be calibrated some. The maf settings for idle is the 50hz slider. Also my gauge and dsmlink doesn't read the same on the wideband. You should look into the dsmlink buffer circuit.

Sorry but I would recommend against this.

Unsteady idle could be caused by LOTS of things. First do a boost leak test, also check your grounds. Post a log. Adjust your biss. Check your tps voltage also.

It probably has nothing to do with the DSMLink tune. Like 96eclipzGsT it probably the BISS, dirty throttle body, bad ISC, leaks, etc...

If you have 2g maf selected in DSMLink then you shouldn't have to worry about fine calibration until you really want to dial it in. For an idle issue I'm gonna go with 1gDSM4g63 on this one...start checking your ISC, BISS and look for boost leaks etc.

in dsmlink theres only a selection for hacked 2g which i have no idea what that means. as far as boost leak, my vacum at idle i think is like 18 or 20 and the car boosts fine, once it gets warm actually the idle isn't as bad. i dont have a 02 sensor connected, could this be a problem?

whats dsmlink buffer circuit?

also would using the narrowband simulation help with idle as i have no 02 sensors connected?
