Re: Lm-1 to Tweecer hookup
OK, did you get a chance to read the voltage at an idle? gt90stang may have a point.

Re: Lm-1 to Tweecer hookup
I think I am going to try this method this week (through the EGR). Clint, isn't this how yours is done? If so the pin listed below is for a sn95. Is this the same pin location on our cars?

Re: Lm-1 to Tweecer hookup
Yes, Mine is wired up to the the EGR sensor. I did not want to cut any wires so I cut a plug off an old O2 and crimped on a new pin for my WB. Now it is simply plug and play. I just unplug the WB and plug the EGR back in for emissions and vise versa.
I believe the pin is the same. Pin 27. I will have to check when I get home. I know the color of the wire is different for me. I am using an 86 wire loom.

Re: Lm-1 to Tweecer hookup
The DataQ is much cleaner. Start with basic troubleshooting, connect the DataQ to your PC and start the DataQ software then ground input 1 to input common and see 0V. Then connect input 1 to one of the digital inputs you should get a change to ?V (sorry can't remember but you can measure it with a DVM). If that works then the USB to serial converter and DataQ are working right. Then you just have to get Calcon reading it correctly, use the standard 1-2V innovate.dbf file. You can do the same thing using a 1.5V battery or other voltage source into the DataQ and datalog to see if Calcon records the voltage input into the DataQ.
The USB to serial converter has software settings that have to be right also. Try 9600 baud (not sure what DataQ really needs I'm at work), 1 stop and start bit, hardware handshake...yada yada yada. Next make sure the LM-1 is setup correctly...reset defaults if you have to. Do a free air cal and measure the voltage out of output 1 on the LM-1...should be around 2V or so (maybe higher I'm not sure). Once you get everything working connect it all together and it should work. As you can see there is a lot going on here and everything has to be correct to work right. Also if you go the EGR route you have to disconnect the EVP sensor and disable EGR or it won't work right. Good Luck, Don |

Re: Lm-1 to Tweecer hookup
Oh yeah one gotcha is that installing the DataQ software might mess up the Calcon software. There is a fix in the software section of the Tweecer site.

Re: Lm-1 to Tweecer hookup
ok. the data q software is installed and the item is calibrated.
It still does not read correctly in Calcon Calcon will read about 2 points off at idle and as soon as crack the throttle it will display 0.9-1.2 a/f in Calcon. I have the dataQ grounded with the EEC right now. I am going to try running a ground to the battery in a little while |
