I have since used an Autronic model B very expensive but it works fine, Just a word of caution, don't fixate on getting a particular AFR as there is no "sweet" number every engine like their own AFR. Good luck. Joe

Im not looking for something that is going to tell me 'cast in stone tuning tips' just an additional tool to make better raceday adjustments, giving me a better idea what the car is wanting on one pass instead of 3 or 4 passes. Thanx for all the feedback I have recieved so far keep it coming boys, thanx,Dion

i used a innovate lm-2 and was able to get afr to 12.5 all the way down the track,i made a bracket that attached to the unit and hung from the rear veiw mirror,it also had a play back feature that when you where done with the run you could play back on stie but it had soft ware that was real easy to work,rpm and afr along with the air data you collected it got me in the ball park with unproven carb modifications ,i have it for sale on ebay
if your interested item # 110476677274 it is also a scan tool

pm me if you have any questions gmonde

Wide band O2 can be a great tool. Just like anything else, it depends on where your A-F ratio is now as to to how much improvement.

I sell the Racepak and Innovate lines.

If you are looking for the most economical setup I recommend the older LM-1 for race cars with MSD ignitions. They are $279 you can add RPM for $99.

Racepak has a O2 sensor to go into any Vnet system and they are $359.

I have had customers make major gains with cars that are setup for big wheelstands and had some issues with float levels. Also, several guys were able to determine intake manifolds with very unequal fuel distribution.

What do you mean cars that wheel stand? Only carbureted engines not injected is this what you are referring too. What about adding a set of merge collectors does anyone have data? I have heard the fuel ratio going < L > L both ways. Also I have heard that there is no perfect a/f ratio. You should tune until max hp, mph, et. if it starts falling off go back. Rich or lean whatever the car likes. I agree to start with a good baseline 12.8 - 13.2/1 tune up or down and as long as you’re not detonating read the plugs with a good magnifying glass to see evidence of metal transfer.

Hi Dion,

I have used the LM-1 and LM-2 on street cars they work find but on my race cars they don't. If you are going to spend the money RacePak is by far the best i have used, a little pricey but very reliable with no wasted runs. I wasted a bunch with the innovate, it cost me more money (travel expenses to the track, entries and on and on) than the new racepak system. But if you want a used LM-1 or LM-2 I would gladly sell them.

Just my Opinion
