But the ones you guys are looking at dont have much data logging and external inputs , do they? its good that it covers the basic engine details, but it doesnt have 4 wheel speed sensors so yoou know when you are gettign wheel spin or locking brakes. I am not sure if they come with the software that you can overlay your laps and compare times. Not sure you can run pyros to get brake temperatures or pots to get roll and pitch. Cant log A/F or fuel rail pressure
So not saying all that crap is required, but if you are spendign money on a unit, it pays to get as much data logging and analogue inputs as possible. If i am wrong then apologies, but when i looked a long time ago the Stack units were very expensive if you wanted data logging and extra functonality.
I bough an AiM MyChron in 2004. I like it, but if i had of waited until a botu 2006-2007 i would have been able to get a way better dash for less money
