LC1 Issues

[nonnieselman]

So i finally got around to putting my new S475 Turbo on and unwired my LC1 from under my truck and rewired it under the hood so the Sensor would be in the downpipe.
Fired it up and went for the first boosted test drive. wideband worked for about 2-3 minutes then went to 7.5afr.. i can restart the truck and it works for about a minute..

Yall got any ideas? I redid the ground wires to be safe. Still no worky.


My new LC1 will be here today, but id love to get this one working so i can put it in the Samurai so i can tune the 4.8..


Any ideas?

how close is the sensor to youre turbo ?
it maybe already cooked due to heat

[nonnieselman]

prolly 16"
Same as what KBRacing96 does on all his turbo kits.

Thanks joe,
i tried that already and it didnt work.. so i figured id just buy a setup from taquickness.


I got the new LC1 in and finally found a Serial/USB and got it programmed.. why the heck do they still use Serial connections? Thats 20yr old technology :(

Now i have a wiring issue, the LC1 and gauges come on and go off when they want to.

( lol, actually serial comms dates back to the 1960's... 50 year old technology )

Sounds like a bad power/ground connection.

I knew it was old.. heck i studied that crap and computer programming in college almost 10 years ago..

I gotta run some more wire in my rats nest of wires under the dash..

Well im having trouble with my LC-1. The gauge reads fine that I have attached to it... But the flash and scan box isnt getting any information.

I've driven a little it and logged at least twice and just all the sudden nothing couple starts latter.. not getting anything.

I checked the Flash and Scan box and it says that there is no wide band connected. I tried recalibrating the heater and the sensor. Thinking that would help but Im still getting nothing when logging.

Thanks

Are you using serial comms, check your serial cable and the RJ12 plug on the end of it...

also make sure that the null terminator plug (looks like a blank 2.5mm stereo plug) has not come unplugged.
