We got my LC1 DB kit installed lastnight

All the grounds run to the radio ground, all wires are soldered real well and heat shrinked

My buddy has this same setup and installed the same way

His reads 22.4 when he calibrated it

Mine only read 21.9 and will only read a 21.9 max

When we installed it, it was in my garage we pulled the car into and let run for a bit and he also had a smoke in there

Would this have caused a bad calibration?


Thanks for the help

Ran into another issue today

The led is flashing 4 times and the gauge keeps flashing 7.4 at me

the instruction manual that came with the LC-1 has an explanation of the error codes.
you can also download the .pdf from innovate's website.

its in appendix C, on page 21

Dealt with the heater calibration problem

PJ - Is it normal that my LC1 would read 21.9 after a Free Air calibration and Newts reads 22.4 after free air calibration?

Both installed the same way

I think it depends on the parameters programmed into the controller.

I'll try to take notice what mine reads maxed out tonight to see if there's any difference.

Please do so i can compare

cruising max AFR sweeps to around 18.5ish on decel but thats irrelevant.

programming of the controller you can set the spread, but I wouldn't worry about the accuracy.
As long as you did a free-air calibration, all is well.

if you pump the LC-1 into HPT tho, be sure to do a voltage offset so the AFR number in HPT is the same as the actual AFR number.

Could you explain the Voltage Offset procedure PJ ?

as far as calibrating it ... you do both calibrations with the car off including the heater calibration
to do the AFR calibration, let the car sit for 8 hours..turn the car on, let the sensor warm up .. then ground the wire (or push the button if you installed it) .. turn car off for 60 seconds, then you can start the car and go.

procedure is explained in the manual.

once you've started the car there will be gases in the exhaust system so maybe it wont read max lean. also, you might have a slight voltage offset depending on how everything is grounded.

everythings explained in the documentation though. running it to the radio ground might not be the best

Im having no issues with the install

Everything is grounded together and to the radio ground which might not be the best i agree


Could you explain how to adjust the voltage offset for HPT ?

Voltage offset setup is explained on the HPT forums.

You need a computer with a serial port to program the LC-1 so you can perform the offset test and get it bang on. That was a bit of an issue for me since laptops haven't come with serial ports in YEARS.
