Default I seriously hate this ******* car

put my mspnp in this morning and for the life of me cannot get the ******* timing anywhere near 10 degrees, it was set at 6 before i put in the megasquirt. Now i'm out there ******* with the timing for an hour and now my tach does not work. the closest i can get the timing mark is on the other side.

your not touching the CAS and just changing the angle in megatune right?

In MegaTune>Spark>spark settings

the fixed angle should be set as 10 and NOT -10 which I suspect it currently is.

-10 means it uses the spark tables, and other figure without the '-' means use that figure as the static timing.

Follow the timing set procedure EXACTLY per the manual. :gay:

The motor does start and run, right?

ok i fixed the timing, i was being dumb and didn't notice the "-" in front of the 10, change it to straight 10 and set my timing, idles great now. Tried to take it for a slow spin around the block, as soon as i give it even the slightest amount of gas it stumbles and almost dies. gotta sort that out.

probably need to give it the correct REQ FUEL number for your largers injectors...

Yep-- the manual covers scaling the map for different sized injectors as well. You'll need to change REQ_FUEL, but also your cranking pulsewidths and lastly your acceleration enrichments which are static PW settings and with 50% larger injectors spraying about 50% more fuel than needed when you tip in... meaning you'll fall on your face when you get into the throttle.

BTW-- I've made a couple improvements to the base map as well that I can share. Shoot me an email and I'll send it to you when I'm back in the office. I'm going to post them up for download as well...

i did read the manual, i missed one thing, i did set the reqired fuel to 8.7 which should be close enough for my 305cc supra injectors. idle is perfect, i just need to set adjust the fuel and timing tables. how much do i need to mess with cranking pw if it starts just fine?

if it starts fine as in like stock your cranking PW is perfect, no messing

Cranking PW can be somewhat tolerant to change... or it can be a pain in the butt... if it's fine at a dead cold start, and at a hot start, and 'warm starts' in between, then it's fine to leave it alone.

You probably will want to adjust AE though... that's how much extra fuel is squirted at tip-in throttle and it's pretty touchy to being way off.

im not sure what's going on with this thing, as soon as rpms go to ~2500 the thing dies and injector pulse width goes to 0.0, rpms drop

I have a MSQ with 305s that I used, might want to steal the fuel table and some of the settings from that....not sure if that was before or after the lc-1 crapped out on me....(see settings thread)
