    yes I have the spark inverted.

    I just pull the wire off the coil, I'm loosing spark for while, when I let the car sat for a while it will crank up and run then dies, because it has lost spark. Anyone has any Ideas.

    I just got my car running but the problem now is it runs for only 20- 30 secs. and dies, I have been playing with the after start enrichments setting but can get the car to stay ildleing. I have been reading the manual about calibrating the TPS, but when I input the reading megatune tells me the " value looks funny" I have try to adjust the TPS by moving it back and forward, but any reading I input in the calibration box tells me it's looks funny.

    This how I'm calibrating the TPS.

    1 tools

    2 click on get current

    3 click on cancel

    4 click on tools, clibrate TPS

    5 ENTER the value plus add 2 ( so if I got lets say 34, when I ckeck I add 2 and enter 36)

    Is the way to set the TPS calibration? I not sure it this has anything to do with the car not running for more than 30,seconds or not.

    Thanks

    Hey Jerry,

    I'm still around and still having problems with my unit. I have only had the car running for a week since the installation in may. I have lost spark again I do have injector pulse but that’s it. I could only get the car to run by installing a GM HEI. module when it ran for a week. I'm in Indiana do you know of anyone in the area that can helps I'm willing to composite them.

    It's ironic how it was me that asked you build me a box and document the build for us Z guys, and had my friend draw up the relay board diagram to go with the documentation, and seems like everyone can get the cars to run but me . LOL

    Matt,

    It click at idel and while I'm driving. I do not have a PWM valve. I place my hand on the three realy and found the far right relay (THE ONE NEXT TO THE 37 PIN CONNECTOR) is the one that's clicking .

    I just got my 240zt running, and notice the realy board does a lot of clicking while I'm driving. Would anyone know what would cause this, or is the clicking normal.

    I have the same problem, the coil only fire a few times and than stops, the tries to run but dies. I send the ECU back to DYIAUTOTUNE, twice. The first time he found the the unit have gotten hot and fried the vb921, also lost one bank of injectors which he fixed.The second time he found nothing wrong, I got the unit back friday and the skark still does not work, I have replaced my coil,check all my wires, grounds, still nothing.I have been fighting this problem for a month now. I have serched the megsaquirt forum and have not found anything that could help.I'm seriously thing of buyng SDS. When I think of all the money I have spent on megasquirt I could have had SDS. Lets hope someone here can help us.

    I may have found out why the car will not start, megasquirt is not firing the coil on every turn of the engine. I pulled the wire of the cap an grounded it to the body of the car and the coil is friring every so often. Would anyone know why. when I move the wires going the the TPS the coil fires and the fuel pump runs.

    I had the same problem using you file in the sicky as it it not compatiable with my code, Thanks for looking over my file.Looks like I still hav a lot of work to do. I have 370cc low impedance injectors. The reason I went to simultaneous injection is I lost bank# 1 on my injection drive, and now I'm running all the injectors of bank two

    sub. in spare tire well

    in Non Tech Board

    Posted

    I'm thinking about putting a 12 sub in my spare tire well. What I would like to do is install the speaker in wood and screw in down in the well. I would also install sound deadening. Has anyone done this and what is the Sound quality . Or would it be better to build a box to fit down in the speaker tire well and.

    A little update I checked the voltage at the injectors and found that I have 12 v on 1-3, both side of the injectors and 4-6 have 12 v on one side and 3 v on the other side,and injectors 4,5,6 are very hot. I checked the relays in the relay board and fount the far left relay (as you are looking at the relay board) is hot as well. Could this mean a bad ground?

    I had my car running not perfect but it ran, (lean) so Friday I found a map that looked good and plugged it in . took the car out and it ran really good for about 2.5 mile and than it died. I tried to get it started but couldn't so I had the car towed home. The rest of the day Friday and the weakened I tried to get the car started ( Adjusted and recalibtared the TPS). I pulled the plugs and as I suspected they were fouled . I noticed that 1,2,3 were not as bad as 4,5, and 6 as they socked. I decided to turn the car over to see if any gas would squirt out of the holes and sure enough 4,5,6 shout fuel out all over the car and walls. I then drained the oil but it was mostly gas that came out. Replaced the oil installed new plugs and the car started but ran for a few second and died again. So I pulled out the railed with the injectors still attached and turn the switch to on and as I suspected 4,5,6 dumped a lot of fuel, 1,2,3 did not dump any fuel, so I removed the connector from injector #4 and #3. I installed the connector for #4 to #3 injector and turn the switch to on and #3 dumped a lot of fuel as well as 5 and 6. This leads me to be live that something is wrong with the bank that runs 4,5,and 6. Would you guys have any idea, were I should start. Could something not be set up right?

    Thanks

    Thanks guy's I have tried all for your suggestion and the sensor still does not work. I contacted the manufacture tech guy he thinks the controller is bad. I am sending it back today, I will run the car on the narrow band until they send me a replacement.

    HI Brian,

    I dont have a stimulator, so there no way to test the ECU

    I did run the Log works on the lap top and the gage on the laptop shows reading.

     

    I programed both out puts and both shows nothing

     

    I recalibrated the LC-1 yesterday, but I can do it again.

    I did check the volts on both out puts and both show 28mv. this is before and after the 470 - resistor

    I have program the 02, set the EGO in megatune to wide band and set the 0-5 v 10-20 AFR lC-1 in the ini files. and the sensor still does not show any readings. I also have a 470, resistor in line with the ECU.

    I can't megesquirt (megetune)to communicate with my LC-1 wide band, I have try setting it in the ini file but it still does not work. The sensor read when I pull up the log work gage on my laptop. It reads 22.3 afr. lane.I did the free air calibration when I installed the sensor, and have reset it a few times still can get megesquitr to communicate with the sensor. When I pull up the real time display, and the VE table 1 in the tunning tab everything reads except the 02. Would anyone have any idea why megesquirt is not communicate with the Lc-1.

    Also just got the car running when the boost start to come on the car pings, at aroung 2psi. and aroung 3300 rpms. if I stay out of the boost the car runs fine, another problem is the car idles for a while (about2-2.5 mins.)and then stops

    Well the weather has finally gotten better how about a drive this sunday.What I was thinking is we cruise for a few hours and that get a bite to eat.We could meet around 3 PM drive until 6 PM or so and then get some dinner. Times are not set in stone we can adjust it if needed.Send mail if you can make this event. Our next monthly meet will be June 6, we will go over plans for our cookout on June the 24 and the zcar show in Indy on the 17
