New Build...Won't 'Start'
2 Attachment(s)
New built motor, new MS3x (I built), LS Truck coils, DW200 Pump, ID1000 injectors, e85.
I took a basemap for fuel, and scaled up 30% for e85. My timing map is ridiculous right now...I think I threw too much timing on my last motor so I'm a bit gun-shy. Tries to start....sort of does...but dies almost instantly. More fuel...Less fuel....doesn't seem to care. I know I just don't have something set right, and I keep searching and trying....two days now....I have a headache. Help? |
Are you 100% on your idle VE table values? Your highest value is 82, maybe you're dumping too much fuel in?

The log doesn't show any PW although it does make an attempt to start. It also shows a lost sync reason of 2. Do a composite log of the cam and crank.

What hector said^ your ecu is literally never trying to inject fuel. It is probably starting and running on just the priming/cranking pulse.
We definitely need a composite log. And more details about the motor. Looks like a 36-2 crank wheel. What cam sensor setup? Lost sync reason 2 means it is seeing the missing tooth at the wrong time. Is the trigger wheel on backwards? Post a picture of the crank trigger wheel at TDC. Also your tune is set on Fixed timing. So its always using 10* of timing. Have you checked the Trigger Angle/Offset? I see 0 in there, is that correct? |
Hey guys, Thanks for the input so far. I forgot to grab a log last time I played...I'll get back to it tonight. However, I did finally get it to run...not idling, but I expected that.
Apparently I didn't add some info that I was thinking about. Car is a 2004 MazdaSpeed, but now has a 99 block/head. 11:1 Supertech 84mm pistons, Head shaved .020", 36-2 SuperMiata Trigger Wheel and damper. Previously had an MS2e running on old motor/stock turbo....probably should have started with some of my idle settings/etc from that tune...doh! Cam sensor is factory, used a new factory Crank sensor (my old one had some gouges from being a touch too close I guess). Again, I'll get a current log tonight..Appreciate the insights. I haven't driven this car since last July....been a slow process with the build (well, slower than I wanted). |
Went out and played with the car a bit. Almosts idle until it hits 190 degrees, then spikes rpm to 4k until temp drops below 190,then instantly drops to around 1k.
Was going to get a log, but went out to Break-in the motor since it is running. Battery cable wasn't tight, and the positive lead came off... Voltage spiked, and then nothing. Awesome! Will check the Ms3x tonight. |
No bueno. MS3 has no 12v or 5v anywhere on the board. JimStim is providing power, and as soon as I turn the stim on, the power led very briefly flickers dimly...then nothing. I don't see anything burnt on the boards anywhere...
I've checked at U5, Q9, Q12, etc, etc.....nothing....where do I look now? |
