Ive used the LM-1 for a few years now and really like it. Especially the more I add to it for logging purposes. I will be adding 4 egts to it soon. My old street cars were all VDO and I always ran a EGT guage and would tune the engine off of that. The egt reads slower but you can get a great tune with it instead of the afr. Just beware of cheap afr guages out there.
The new LM-2 looks REALLY nice compared to the first gen. You may wanna consider this if your really serious about logging/tuning.
