Speed Limiter E37

[Bearce Sr]

Hi all, trying 2 set speed limiter 4 120km/h changed H0129 from 180 2 120, also changed H0161 from 132 2 72. still lowest speed is132km/h what else needs changed? TKS Ed

Yeah, you need to set the Speed Limiter source {H0156} to 'ECM', some vehicles are already set to that, if it is not the ECM does not control the top speed.

[Bearce Sr]

Tks, H0156 is set ECM any other ideals?

[GMPX]

I'm not sure Ed, it seems like you have done everything that needs to be done. Of course most of the time people want to remove the limiter, not decrease it, so perhaps there is some other calibrations hidden within the ECM that limits the lowest speed. What OS is the E37 you are working on running?

[Bearce Sr]

OS is 12630187 It's my kids car she has lead foot 2 many tickets

[GMPX]

I figured as much

I see this is an old thread, but anyone come up with a solution? Having the same problem with an E37 running 12635399. Have done all the above, and the limiter seems to have no effect.

This tune shows H0156 as Other Module, but made no difference when it was ECM.

Spark and Fuel limiter options are also enabled, but also made no difference.

Engine just keeps on going, right past 111 Kmh

Nobody but Bearce and myself have had this issue?

[GMPX]

Does yours keep going to the 132 KMH limit like the original posters? That might be the key to fixing this on the E37 if that is the case.

Can't say. This is on a fleet vehicle, and if the GPS reports a speed over 73MPH / 117KMH, its a company violation. That's why It so irritating when the programming doesn't work as it should.
