LM-1 FROM INNOVATE MOTORSPORTS

Jake,
Is the LM-1 the tool most suitable to aid tuning of the SDS EFI system, and if so which model or package would you recommend? The LM-1 driven XD-1 gauges and standalone LC-1 gauges look even handier, but I'm way over my head on this one and would appreciate your advice.

Thanks, Dave

David,
The standard LM-1 is all you need and it's very easy to use. did the fuel curve numbers I sent to you help any with the fine tuning of Herbie?

Jake, the new numbers seemed to help, but there are a few rich spots remaining which require on-the-fly trimming. It's all been guesswork so far, so an instrument like the LM-1 will serve to lock down exactly what's happening and when. Will the LM-1 be able to get all it needs from the serial port within the glove box? Will I need twin 12V outlets to operate both the LM-1 and SDS box? Am I asking too many damn questions?

Thanks for your help.

Regards, Dave

Dave,
A splitter installed in the existing cigarette lighter will power the LM-1, or you han whack off the plug and hard wire it in to the car with a detachable plug in between.. Thats what I did in all my cars, so I can swap it easilly from car to car.

You will remove the existing O2 sensor from the exhaust system, and utilize the sensor that comes with the LM-1. You can zip tie the SDS sensor out of the way when not in use and vice versa. If your exhaust wasn't already coated you could install a second bung for the sensor..

I have tried using the SDS sensor with the LM-1 without good results, the stability just inst't there.

If you want to save the money on the LM-1 I'll send you mine for a few days.

Jake, thanks for the loan offer but I can put this to use on my other cars, especially the one with four Weber 48 IDFs. Based on the descriptions below, is there any merit to the "RPM Kit"? It's not that much more dough.

1) The Basic Kit includes a the Meter, a Bosch wide-band oxygen sensor and cable, cigarette-lighter power adapter, serial cable for PC connection, 9V battery, exhaust bung and plug, CD and manual.

2) The RPM Kit is comprised of the basic kit plus the LMA-2 Auxiliary Input Cable. This cable contains a circuit to convert a tach signal into an analog RPM singal that can be logged by the LM-1. This cable also has 4 additional terminal screws to tap into and log other sensors in your vehicle.

Thanks, Dave

I'd get the standard kit.. It'll do everything you need without a bunch of confusion....

Thank you Jake.

We've tuned three vehicles with a basic LM-1: two Bugs and Dad's POS truck. In each case, less than an hour of tuning resulted in what felt like 75% more power and a milage increase.

The LM-1 is pure sex.

my little tid bit on the rpm converter option.
this will allow you to hit the record button and go drive with out having to keep an eye on the unit. then you just go back with your lap top and review and see at what rpm is having a problem.
Although i am thinking wide open throttle too.
you may need a throttle position sensor reading to judge in regular street driving. so you might see where it stumbles because of rapid throttle movement enrichment, etc.
just a thougth.

Mike,
without the system logging MP long with RPM and AFR it doesn't do a lot of good...

Yes, you can view more things and if it logged MP it would be very effective.

David's issues are with fine tuning, so RPM fuel numbers are not what he needs help with more than likely. The fine tuning is done with MP values infinitely.

mp meaning manifold pressure, correct?
yea i can see where that would be much better then throttle position.
im still old school. wide open throttle.
I only really just getting into understanding all this other stuff since i have been glancing at fuel injection stuff and how they work and program.

I just picked it up a basic LM-1 from the local hardcore speed shop (specializing in late model GM cars). After a couple of the boys came out to goof on poor 'lil Herbie it turned into a regular show-and-tell with the whole staff in the parking lot. Thanks Jake!

SWEET!

Mike, TP won't help in tuning the fine tweeks into the EFI arrangement because MP is dependant upon TP and load, so it's possible to have the same MP at many different RPM dependant on load and gear selection...

basically a tweak of the MP would be similar in result to an air corrector change, where an RPM fuel value change would be similar to a main jet change.

Dave, you will only need the one 12 volt outlet to run the LM1. The controler and lean/rich trim box do not plug into the 12 volt outlet.
Glad to hear the GM boys attempt to goof on HX was foiled. That car will draw a crowd everywere it goes. Lots of cool goodies and the more you look the more you find.

our solution is a far superior one. The rugged and durable handheld programmer is small enough to fit in your glove box and with the provided o2 sensor installed, the programmer stores an air fuel mixture ratio for every point in the fuel map, allowing for quick and easy tuning for either maximum power or fuel economy, or a sensible compromise between the two.

Jake,is your hand held programmer universal or specific to your sds system?If universal are they available on there own?
Thanks
