Bought NateTheShake/neogenesis2004's Ford Mineral Turbo Miata
Hi, I'm a total car noob and picked this up. The car dies %90 percent of the time on full stops. I drove it the other day and the rpms at idle aren't steady. Sometimes at a stop it is fine, usually it will die. After it dies it will take 5-15 seconds before the engine will turn over and it starts. I see the "charge" battery light come on when it dies and asked the seller if it was that and he said it isn't. He knows a bit about cars and I'm pretty sure if it was those small things he would just say it needs a new battery/alternator then "it needs to get tuned right"The car's engine feels fine as long as I don't do a complete stop. Anyone in the Philadelphia area want to take a look at it? There are tons of stop signs/red lights here. :(
Also tell me everything you know about this car. Mods can move this if I put it in the wrong section. What program do I need for my laptop.
Link/info about the car when it was sold on here. I bought it from the guy who traded a 4x4 for it.

RX7 460cc injectors
4.30 LSD from a '99
FM Stage 1 Clutch & stock 1.8 flywheel

Racing Beat adjustable end links
Energy Suspension poly bushings (installed)
Hard Dog Hard Bar
'94-97 brake mod
Hawk HPS pads
Centric OE rotors
S/S brake lines from Moss Motors
S/S clutch line
I also have a set of Boss Frog door bars and frame rails not installed at the moment I might throw in with the car.
The good: The engine runs fine and the car just needs a good tune
The bad: The engine needs a tune! I am still learning the whole standalone thing and never got the tune sorted out.
For what it is I believe the buyer is getting a great deal, but don't expect a show car or a flat out turn-key."

I'd start with the MS. When It left my hands is was stock, running on the stock ECU. Had no issues then. Now it has MS and you say it has idle and hot start issues. So I would guess that both of those things need better tuning. Thats about as much as I can help though, I suck at tuning idle and other **** like that. I would try getting a msq from Brain again, completely reflashing the firmware on the MS maybe, and then reloading the new msq. Then you can at least hopefully rule out the firmware being corrupt. Plus you'll also get a msq that has been combed over for 4-5 years.
Most likely its tuning and possibly parameters setup wrong. Just guesses though.

Philadelphia.
Dell Mini 9" netbook with no free space. I have to buy an external drive.
Windows XP
It looks like I have a lot of reading to do or spend $???.00 to get it professionally tuned.
How much RWHP should I try for(with this setup) without braking something? and what PSI should I stay under?

Just read up on how to tune, I wouldn't say you need to dump money into a professional tune, unless you really want to. Start messing with accel/deccel settings, one at a time, to see if it helps.
I'd say whatever PSI gets you to 200hp is safe and easily possible.

With that reflective sleeve it doesn't matter for **** Trey. I had it like that back when I was having issues with my manifold glowing as red as the sun with the built motor I had in there and it never had a single issue. The hose is fine like that as long as its not making direct contact to the manifold, that sleeve is rated to reflect passive heat up to like 1200 F continuous. Just look back at my build thread if you need any more proof. I didn't even have a turbo heatshield that covered the top. I just used conduit tab mounts attached to the valve cover to keep it from falling down onto the manifold.

UPDATE!: It's been tuned! It no longer dies in the short test.
What kind of power should I be making. I put down 210 rwhp on the dyno. I'm not sure if it was held back a bit because of the 2nd issue listed below.
I have a belt squeal in the alternator. I need to tighten the belt.
I still have a stumble and I end up with missing data to the TunerStudio.
Could Possibly be one cylinder is not sparking every time it should.
or
Could be the CAS
The rpms sometime bounce from 2k-2.5k rpms at idle.
It sometimes dies at random but a lot less than before that the tuning did not fix.( i forget if this was in idle or not)
Possible CAS?
Coil Pack?
Spark plug or wires?
Ignition needs cleaning?
I have a small leak in one of the small coolant hoses on the left side. dripped only a little bit throughout the whole testing

I let them do all the programing.
Here's a comment on the miata;
"we couldnt even get before numbers, the tune was absolutely horrible lol
it was 17.5 AFR almost everywhere accept idle.
just creeping into boost at 3k it was still extremely lean 17-20 afr..
very scary.
on a rich pull with less timing it made 180rwhp
cleaned up to an 11.80 and 18deg timing it did 210rwhp
i was most impressed with the 186ftlbs of tq!
car has an ignition issue though, bad hall effect sensor or crank/cam sensor
every now and then it comes out of synch with the ecu and you get junk in and junk out and it will have a tiny miss and blip the tach off and back on."
