It adds timing as you do it though that way as well since its in a different load for the same airflow/boost. You'd want to drop timing way down to compensate.

If anyone was going to test this I would suggest moving in small steps that you can track like 5-10% voltage changes with nothing else in the tune changed so you can see where it ends up. Lowering the boost as well might not be a bad idea, but then you dont end up in the right load, so maybe just timing and fuel.

OHH your right forgot to mention that. Good catch

that was another thing when tuning it on the skittle to low of voltage the ecu threw too much timing. Just had to find the right sweet spot for air fuel/timing with no knock.

This seems to be a better solution than buying an SAFC just to limit maf voltage.

also if someone does purchase the dasmopar "map clamp" last time I recall (havnt touch one in a few years) that it takes 12 full couter clock wise rotations to be able to start adjusting the voltage limit.

seems like this will affect ecu boost users, so your target load or psi will probably need to change

Or you could just build your own map clamp. (2) zener diodes, a through hole pcb board and a 16 turn pot should do it. Less then $20 in parts from radio shack .

Heres a link to another log of Smogrunner's that shows the 2byte load maxxed out.
