First single & dual channel A/F runs with LM-2

Yeah it is but you put it anywhere near a plug wire and it's not . .. scope it and see.

 

Does the new unit have any internal accelerometers? Nice to see how she actually pulls . . think you're carrying an extra few hundred pounds in the Mondi vs the 308 but she might keep up with my car (on the straight) . . . don't bother trying to go 'round corners fast and pulling close to the "g" my 308 is capable of . . . you might hurt somebody

Totally teasing . . . one of these days I need an F car with a back seat . .. actually no I don't . . I removed my passenger seat for a while

 

And with EFI it stays that way during hard cornering

 

Not unless you add the AUX box which has two axis Accels built in. Also does not have any GPS utils at all which would be nice. Tempted to get rid of the LM2 and replace it with an LC1 and a Datalogger unit with gps. It would be real nice to see what it's doing on different sections of track.

Someone mention additional inputs. Besides being able to handle 1 or 2 O2 sensors it has 5 analog inputs and 2 programable analog outputs standard. You can get more inputs by adding the aux box or some other moduals they make.

 

they are such fun toys!!! . . . that's a good way to go with a seperate data logger . . the only thing I dislike about the LM1 is the unit doesn't work when the o2 sensor dies.

I'm not sure which data logger to go with . . . you thinking about Innovate's latest product? . . . the problems you guys are having with their latest products isn't a good thing though.

BTW you know there's an application for IPOD/IPhone that measures G forces? . . it's like $15-20 . . . I'll get more infoo if anyone needs it . .. P club guys have been playing with it.

this is the Innovate product? . . .and you use LC1's for O2 which just output 0-5v signal which work with any data logger?

What's the price so all the info is here in one place? . . . that's great that it works with the auxbox and hopefully it doesn't need the o2 input to function . . that'd be stupid if they did that.

 

The only stand alone unit I see at Innovate is the DL32 for $500 which has all the sensors built in inside .. . just makes my auxbox obsolete.

The unit you're referring to perhaps requires a computer for data logging?

 

They do have an extension.

For someone else that asked the single channel LM2 is $475 and the dual is about $150 more.

Here is the GPS data logger I was refering to. $965 plus the cost of the LC1 if you want O2 without a real time display

One of my complaints with the LM2 was it was very hard to read the display to tell if you started recording or not. Did they fix this on your new unit? If your holding it in your hand it's not too bad but when you mount it to the dash in a racecar it was really hard to see if there was a little "R" in the black background text in the bottom left of the screen.

 

In the racecar I have the MSD mounted in the passenger compartment and the coil is in the engine bay with the spark plug wires. Don't know what the problem is? I might have it too close to the cable that comes from the msd to the coil?

 

didn't know those helped for cornering

there was an offensive video I posted with a guy lighting up the tires like it wasn't his car ... that car sounds exactly like mine

bummer you don't like new F1 cars mate . .. definitely stick with carbs then

way lean is 14.7 and higher at every point except full throttle . . I could say it's a green thing but it's not . . tons of info about tuning on the Innovate site . . give those guys a chance .. its a bummer your unit isn't giving you clean data right out of the chute.

I wish I could just "jet my way" out of all problems in life (inside joke to myself ).

cheers,

sucks you guys are having issues with these units . . their forum is awesome and the owner answers questions (haven't been on there for 1 year though so who knows???) . . I do recall when I bought my unit the "new products" they were introducing were having a lot of issues but they were all over it on their forum.

no affiliation . . etc.

cheers

 

Keep it below 12 WOT. Probably not losing too much HP if any at 12, but remember you are measuring an average not each cylinder and just like the two sides are reading different, each hole is different. If you are getting 13 or higher WOT there is a good chance one hole maybe reading 12.7 and another might be 13.4 to give you the 13 reading. Also temp, air density etc. You don't want to go out on a cool day and roach the motor. Keep a very close eye on the plugs and check for any signs of lean often if you are going to run anything over a 12 a/f ratio. You will need at least a 10x mag to look to see if you are getting little aluminum balls on the plugs.

The a/f will affect water temp quite a bit. Keep a close eye on the gauges on warm days if you are going to try to run over 12 A/F. I see most guys running 12.5 to 13 on the dyno and then throwing extra jet at the engine when they put it in the car since the key word in racing is "Dynamics" , nothing is staying the same and one thing effects the other. You might get an extra 1 or 2 hp running a little leaner but the extra heat might make it so the cooling system can't do it's job and you lose hp and damage the motor.

 

carb problem only

edit: EFI guys make more power on these days

 

The aux box and several other Innovate products have thermocouple inputs on them . . isn't measuring exhaust gas temperature one of the ways you look for optimum a/f ratio besides dyno? I wanted to play with this but figured a thermocouple on the outside of the header wouldn't be accurate enough . . .thoughts? Omega has a screw in thermocouple but wrapping a wire thermocouple around the outside of the header sure is easy . .. but if the data's no good what's the point.

Russ did you see a difference front to rear bank or did you have an air leak? Can't remember if I saw the front bank richer or leaner and can trim the injectors if necessary.

Thanks,

Sean

 

curious . . .which EFI doesn't? I've never messed with one that doesn't look or compensate for air temp whether it's thru mass density or pressure density calculation.

also . . . I'm not a carb guru by any scretch . . I don't think accel pumps are there to facilitate hard cornering . .. when you're in the middle of a high speed turn at the limit your right foot isn't gonna do anything that the accel pump is gonna care about if you catch my drift (hey no pun intended) .

carbs are inferior . . there I said it .

 

of course there is . . . looking at your car makes me want Webers but I have to keep telling myself NO NO NO

my only experience with tuning accel pumps is with Holleys and a big block going in a straight line . .. that was enough for me . . I keep telling myself

cheers Russ . . all in the name of improving these girls!

 

see shows what I know . . I thought the accel pump was to compensate for the sudden drop in manifold pressure when you instantly open the throttle . . . which is something you do not do at or near the cornering limits of a car.
