Single channel O2

Racepak too. Never had a customer regret going with them. That's what I'm putting on my new Stocker. Phil Mandella told me you still tune by your time slip, the racepak just tells you which direction to go. I have racers call and ask what number to look for and I tell them there's no magic number for everyone. I have customers that range from 12.8 to 13.6 each with fast cars. When you get a wide band Dan, you'll need to go to a test session and work on calibrating your Q-Jet to run the fastest and that will be your "Sweet Spot". Then when you get in different weather conditions your wide band will tell you if you need to lean or fatten it up. One of my friends and Super Stock customers has a Racepak and went testing Saturday with a carburetor that was completely different than the Edelbrock 1901 he usually runs. His car likes mid 13"s on the O2's. He guessed at the primary and secondary jetting and made his first pass. He could feel the car wasn't right in high gear. When he came back and down-loaded the run, the O2's were 15 in high gear. As Phil said, the Racepak told him which direction to go. I feel that a Racepak is one of the best investments a racer can put in his car. Takes a lot of guess work out of it and quickens the learning curve.

x2! I'm brand spankin' new to EFI, just off my 3rd weekend out. Even if someone runs the same combination as you, there can be something different in either the data collection (type or location of the sensor) or other variables that make things radically different. Ultimately, you have to listen to what the car is telling you on the race track to determine what A/F ratio works best for YOUR setup. Took me til 1st round of eliminations this weekend to figure that out! LOL In the ballpark now, though. I still have a TON of learning to do. One of my issues right now is that I have no basis for what the numbers mean relative to each other. Is half a point in A/F ratio a lot, .25, or is a full point a big swing? Along the same line, I'll need to figure out how much change a single number or single percentage point on the fuel table really is.

i have the innovation lm1
got it from sal
push button in staging lanes push button at scales
very easy to use and to hook up
help my car

Racepak by far the best value for the money.
Very easy to use .
They recomend having the sensor in the primary about 12" from the port for optimum performance, but I've tried both the primary and the collector for reading and found similar results, the primary readings are much easier to read as there is no dilution from outside o2.

I use the Altronics O2 Alert. It works great also.

[MOTORSPORTS Innovations]

I have sold thousands of the Innovate O2's in their various models (LM-1, LM-2, LC-1) and as much as I like them, I would recommend a Racepak Sportsman with a single O2.

The reasons are:

1. For any class with qualifying/limited runs you don't have time to mess with glitchy stuff and the RP hardware and software are rock solid. 16 volts can be a problem with some of the other brands as well.

2. If you have a carb/fuel system that's questionable you have to identify the exact spots it's bad (say during / after a wheelstand or at the shift) and the hand held units with the replay on the screen don't give you enough resolution. You have to download to a laptop and look at a graph that is based on a good sample rate. Likewise, if the problem is NOT the fuel system you want to rule that out quickly and with confidence.

3. So if you are going to get involved with the laptop RP has great support of the Windows 7, Vista and of course XP. Their kits come with the drivers for the USB converter and all the laptop accessories you need.

Dan or anyone else call/email me anytime with O2 or data logging questions. I'm a sponsor of the East Coast Stock/Superstock association and race my own junk every week (brackets / Top Dragster) with a million sensors into the Racepak.

The second one does not read the same as the one that comes with the XFI system. Not even the same brand sensor. Very dissapointed. My two only agree around 12-1. If you have a carb, not the XFI, their stand alone wide band records air/ fuel versus time, not RPM. Air/fuel versus RPM is much more useful for tuning. I have seen way too many problems with the innovate deal. I personally wouldn't use it.

I have a carb and they have a accessory for RPM. I'm putting that on when I do the second sensor.

That will make it a lot more useful. I know a couple of guys that need that RPM add-on. Guess it's fairly new?

It hasn't been out long. Check their website. I think it's $160 bucks.
