Basic MS3 No start
4 Attachment(s)
Greetings,
I've got a 1990 1.6 eunos with a Rev built basic ms3 that I cant get to fire/start/anything but crank idles nicely with the stock ecu plugged in so I have fuel/spark modifications -255 walbro -stock injectors -modified greddy kit -bmw vtps -gm iat Attached I included the log of cranking and the tune for it as well. hoping someone might be able to catch something obvious as to why I cant get it to start. :party: |
Must be something small in the tune that were not catching.
I see I have a 4g63 sync loss maybe, not sure if that would cause this. Not enough spark? |
Have you tried a composite log to make sure all the sensors are outputting properly?

Oops I guess I posted a normal log, will post a composite one In a bit. Also my timing gun doesn't go off, but I've physically checked and I have spark. |
Tried test mode for spark and fuel ?

update\\\\ got a new battery as my previous one was questionable and dying got around to doing a composite log and etc. still unsure of what im doing wrong |
Bump, open to suggestions and reviews
|
Did I delete the maf improperly? Is that possible?
|
Don't you have to pull some 10a fuse on early Miatas for it to work with Megasquirt?

looks like it's syncing just fine. is the fuel pump running? |

depends how it was built.

400+ RPM is to high when cranking, but from the later csv the resets look to have disappeared. could you post a new msl.
I'm not sure about the rev built basic ms3, but the regular non ms3x should not be using the ms3x options in inj and ign outputs. Maybe you should check this with rev. |

no, it's not. :brain: looking at that raw log, im going to say it's your tune. I'd have to look at it at home.
Appreciate that. Should be around to punctually respond to your suggestion. |

Map was really screwed up. I'm not exactly sure how Reverant has built it. But looking at your log is appears you aren't syncing.
This is probably due to cam in going in to js10 and not the MS3x. That's assuming these is even a MS3x. Otherwise the fuel settings were really messed up and I corrected those. See if the attached will work. Take another log of cranking and also a composite log of it. Click the Diagnostics tab in TS and click the save to file check-box and then log cranking for like 15-20sec. attach both log files. |
The cam input is indeed on JS10, and not on MS3x CAM in.

looks like I should switch the cam back to js10? |
didn't you keep the msq it came with?

I did. It would be one of the msq's I posted within the thread. Anything I might be missing here to cause a no start? |
