tooquick260 Posted April 20, 2014 Share Posted April 20, 2014 Well the install is done. The computer communicates to MS3 pro. I have sensors working tps, map, 02 wideband, coolant, reads 10 degrees timing during cranking with out fuel pressure and pulse width moves while cranking. I have done the injector test and the coil/spark test. They all click/fire at the appropriate time. I could not get the fuel pump to work off the MS3pro negative ground so have it wired to ign on. I have fuel pressure. While cranking car does will not start. I get a random fire, more of a misfire. MS3 Pro N42 head Stage 1 cam 240sx tps 500cc injectors Ign 6 coil tower AEM air/fuel wide band 83 turbo dizzy DIY optical disc I think that is all the info you need. Here is a data log of an attempted start. Dont know if this helps. 2014-04-14_09.50.00 - 260z log1.zip Quote Link to comment Share on other sites More sharing options...
madkaw Posted April 20, 2014 Share Posted April 20, 2014 What reads 10 degrees while cranking-timing light? Quote Link to comment Share on other sites More sharing options...
mattb3562 Posted April 21, 2014 Share Posted April 21, 2014 Have u checked your trigger logger to see off crank signal is consistent? Also, I'm more familiar with ms2, but does your ms3 require a cam signal? Are you firing batch injection? Sorry, I'm usually on my phone and can't look at .msq Quote Link to comment Share on other sites More sharing options...
tooquick260 Posted April 21, 2014 Author Share Posted April 21, 2014 What reads 10 degrees while cranking-timing light? The gauge cluster ignition advance. Have u checked your trigger logger to see off crank signal is consistent? Also, I'm more familiar with ms2, but does your ms3 require a cam signal? Are you firing batch injection? Sorry, I'm usually on my phone and can't look at .msq No I have not checked trigger logger. No ms3 does not require a cam signal and I can run batch fire, semi or sequential injection.

tooquick260 Posted April 21, 2014 Author Share Posted April 21, 2014 (edited) I have not. Will get help this week. Need someone to start car so I can see timing light. I am setting base timing with rotor phasing suggested by Matt at megasquirt. Should get timing base set.

madkaw Posted April 23, 2014 Share Posted April 23, 2014 Ever get your timing checked? Quote Link to comment Share on other sites More sharing options...
tooquick260 Posted April 24, 2014 Author Share Posted April 24, 2014 yes got the timing to show up with the timing light by dropping the tooth #1 angle to 226. car almost starts but will not keep running. timing was reading 5 degrees by the timing light.

madkaw Posted April 24, 2014 Share Posted April 24, 2014 Are you using a standard timing light or advance light. Try to get it right on 10 degrees. My trigger angle is 285 degrees, so it doesn't matter where it's at as long as it jives with your settings. I can't open your file but make sure you are using the right spark setting. I imagine you should be set on wasted spark, not semi sequential. Quote Link to comment Share on other sites More sharing options...
tooquick260 Posted April 27, 2014 Author Share Posted April 27, 2014 (edited) I switched from seq to batch and got it to fire and run. Roughly. I picked up some new plugs and will install tomorrow. I will go thru everything again tomorrow. Edited April 27, 2014 by tooquick260 Quote Link to comment Share on other sites More sharing options...
tooquick260 Posted May 1, 2014 Author Share Posted May 1, 2014 playing email tag with matt we got the car to run on sequential. he had me switch trigger 2 angle to rising. car runs poorly but better. working on it a little when i have a chance.

Kirkster Posted May 3, 2014 Share Posted May 3, 2014 well it is running... I am wiring my MS3 Pro right now. Just finished with all of the sensors except the O2 sensor which I have laying in a box on the work bench right now. I am running a crank and optical dizzy for the sequential injection and sequential LS1 coils. I am just now looking at where to solder the MS wiring harness to all of my custom wiring as my car had no sensors before since it was a 73 240Z. Looking forward to hearing how things are going...

tooquick260 Posted May 4, 2014 Author Share Posted May 4, 2014 As far as wiring I did gm weather pack connectors for most of the connections. Wires that will be wired thru a fuse or a relay I have left longer than needed or with butt and male/female connectors. Those will be redone once the car is tuned in as what I feel a good driver. O2 sensor I used the AEM drill hole in pipe, they have a strap the goes around the hole and has the bung for the O2 sensor to screw into.

Chris83zxt Posted May 5, 2014 Share Posted May 5, 2014 O2 sensor I used the AEM drill hole in pipe, they have a strap the goes around the hole and has the bung for the O2 sensor to screw into. That's a good idea for those of us that can't weld or don't have access to one at the moment. I bought a couple of prefabbed downpipes with O2 bungs already installed and chopped them up until they fit and then had an exhaust shop do the welding.

tooquick260 Posted May 5, 2014 Author Share Posted May 5, 2014 Yeah that will work as well. I have the down pipe with the O2 bung in it. But I was running the stock ecu before that used a narrow band O2. I wanted to have a gauge to read wide band and with the strap it was easy.

tooquick260 Posted May 5, 2014 Author Share Posted May 5, 2014 (edited) I'm off to the dyno this morning. Well get back to what I end up with. Edited May 5, 2014 by tooquick260 Quote Link to comment Share on other sites More sharing options...

tooquick260 Posted May 20, 2014 Author Share Posted May 20, 2014 (edited) Well I put the cat before the horse. Car was still running on 3 cylinders. I got no where with it that week. I did recruit a guy from modern day motorsport to look at it at my house. He could not figure out why it is not firing or running on all 6. I had to leave town for 2 weeks and decided to take it to his shop. Last week he rechecked everything that I had checked. Compression, wiring, fuel and the test that the computer checks. All injectors will fire in correct order, all spark guess at correct sequence. He is going to see how it starts and runs in starter fluid to see if it is fuel Been emailing Matt at DIY. He is stunned as well. Edited May 20, 2014 by tooquick260 Quote Link to comment Share on other sites More sharing options...
tooquick260 Posted May 20, 2014 Author Share Posted May 20, 2014 While running tried using starter fluid to see if it would clear out. Did not help. Quote Link to comment Share on other sites More sharing options...
