After you check for fuel pressure go ahead and log some cranking and we can look and check for anything obvious.

 

I'll try that when I get home.

Will do!

 

Silly question: have you tried the 'test' option for both spark and fuel to see that they're both working?

 

Nope. Is that a tunerstudio thing?

 

I'm not sure. It was definitely in Megatune though, but I am not as familiar with Tuner Studio... yet.

 

Guess I'll be giving that a go also. Thanks.

 

also check what firmware your running since that can make a diffrence, and i think the test outputs is in ms2 and up, i didnt see it when i loaded Astros MSQ but then again i didnt know what firmware he was running.

 

Ill open your .msq in a few minutes

Be easy on me guys, i converted all his pw values from 550's to 1000 cc's in about 5 minutes and i was tired, I may have made a mistake.

Also, cranking rpm was put down so low due to the battery. i always thought it needs to be lower than actual cranking because that is what causes the fuel pump to fire. We can play with that to

EDIT:

Yes I use megatune. Still see no point in tunerstudio, especially because autotune costs $. megatune does the same ****.

 

the only change that needed to be made was the req_fuel.

 

So it runs?

 

No, I believe 240 to miata converted his own 550 map to work on 1000 injectors by multiplying his fuel map by 1.81 instead of just changing the required fuel.

 

Naw i changed the req fuel but if you guys are saying its around 3 sumthing that means its still the 550 value. I changed it but was doublechecking my work by typing in the old values (to see what AFR i used last time to calculate it) . Looks like I probably didnt finish with the updated value

Starting up my laptop now. Martin ill send you a new req fuel # to put in and then start this BITCH. I'm on a plane to Georgia at 2pm, id love to know this thing is running before then.

 

Sweet, I am trying to figure this ---- out rite now. So far:

New fuel filter
Replumed the fuel pump in the tank (so there is no doubt)
Fucked with the fpr but have yet to achieve glory/pressure
Blew in the map signal line and it moved
Set required fuel to 3.2
Cranked the car and there is fuel on the plugs again (pulled one and let it evaporate)
Set cranking rpm's to 200
Cried like a sissy girl
Played with my CAS to see if anything would happen at either extreme of timing (seeing how it is centered now)

Battery looks good after trickle charging for 2 days but am only hitting ~250rpm's. Going to log a cranking in a bit.

 

Also couldn't find any nifty "test" options in MT

 

Ok guys... I think the REQ FUEL does looks a bit off. I tried basing it off of his old value, which was probably off too and I compensated for it when I tuned his car. The original guy who helped him in Hawaii didnt understand the concept of REQ FUEL at all!! he had the VE at like 175 in some cells when I first saw this cars tune. I did some work to clean it up, but may not have finished.

1835 CC (somewhere around there, i forget what you told me your engine was)
4 cyl
1000 cc/min injectors
afr of 13 i think. this may be the problem

Martin try using a value of 3. Not sure this will solve your problem, but its worth a shot. WE WILL NEED TO RE-TUNE so be carefull. if your req fuel isn't really scaled the same way your old one was it may be all too lean or too rich.

 

Thats in tunerstudio. The one good thing that program does have

 

Also try improving that ground on your coil packs. The one that we just kinda threw there last minute. Get it to a good solid ground location and check continuity.

Sorry for the triple post. just dont want to edit it and have you not see it.

 

I'm calculating 3.6, but whatever. Should still run on 3.0.

 

yeah i got 3.6 with what I posted above.. but i think he should try 3

 

I moved the coil pack ground to the intake manifold with the engine grounds.

Here are the files.

Also when I cal the tps with it unplugged the value is 75, 222 when plugged in. Thought that was interesting.
