NEW Added Item - LTM Min - Max Limit

[BigDaddyCool]

Does anyone know what the values for:

LTM Min Limit: 1.2500
LTM Max Limit: .8000

Refer to? It controls the Long Term Fuel Trims which is great, I basically want to strip mine down to run a might tighter setup so it doesn't 'over compensate' and drag that into other cells.

Has anyone fiddled with it?

To lower the amount you will allow LT trim, you need to set those values closer to "1". Eg setting 1.1 and 0.9 will allow +/- 10% LT trims.

If your trims are high, then there's a problem with your tune and you need to address that problem... reducing the computer's ability to correct the problem wont make the problem go away. I would suggest leaving the factory settings for the LT trims and 'tune' the trims down.

Yeh nah my trims are quick changing and within +-6% .... i just dont want it overshooting rich basically...... id rather stay a tad lean

everyone has different ideas on trims but i tend to have them all zero or a tad richer but not much..but a different story when W.O.T Cheers bret

So my question is, based on these settings, is that what the PCM uses to report Lean/Rich DTC's like P0171 or would it stick to the current +/- 25%? If it defines new limits than it could be used to tell you something is going wrong a tad sooner.....
