I have no stand alone installed and mine does that too, but not at start. I get that effect at random times. Usually when I lift off the gas. Seems worse in hot days. And more so with the A/C on....

its your tps, the 89-93 have a on/off switch essentially for the tps, when i went standalone i went to the bmw vtps. i dont know if you can do that with the link though.

Shouldn't work better than that? Maybe it's just not working right... I don't remember if my '91 BRG did that or not. Maybe it all started after the SC install...

RedTurboMiata

make sure that link doesnt call for you to unplug the stock tps. most standalones do for the reason i described above.

I'm going through your MSQ making alterations. Are you seriously running a narrowband o2 or is that just an incorrect setting in the tune?

What are you using?

RedTurboMiata

it should be set to the 0-5v i think lc-1 settings. its a prosport evo, they use the lc-1 output readings.

sixshooter

It wasn't. It is set to narrowband. I have an LC-1 so I will change your settings to match mine and we will see if that works better.

Did you dial in your spark to 10 degrees with a timing light when you set your base value when you installed the MS?

RedTurboMiata

i opened it up on my computer and it says lc1. is that by chance keep in a different file, i think the .ini file is config stuff.

Yeah, I saw it was for the secondary o2 after I posted that. I've been up too many hours. See if this will run on your car. I changed a bunch of stuff but not everything I could have. If it doesn't run you can play with it or just revert to what you had.

Cars down for the count ATM, the wideband bit the dust a few weeks ago. I should be getting it back Wednesday. So I will try it then.
