6v92 detroit
Hey guys I work for a fire dept and we have a 88 pierce fire truck with a 6v92 detroit in it. I was wondering how to turn the fuel up on the truck or find info on how to do it. Thanks

Brain box? DDEC? If it is, it will have a box on the top of the engine. That, we will need to know before you can start playing. And whats going to happen when it gets taken in, and they find out. That "SOMEONE" has been doing non cert'd mods to the engine? I'd leave it. No fire is that important to get to...my .02

6V92's are 2 strokes, and purely mechanical.
Don't turn the fuel up, makes no sense in that application. You need a stone reliable motor, even if it takes a minute or two longer. I'd rather have a fire truck arrive a couple minutes later, than a fire truck burn up the motor and never make it.

there's lots and lots of 2 stroke DDEC engines running around. the electronic unit injector was brought into the 2 strokes in the 80s - early 80s sometime. DDEC 1 I can find out the exact year tommorrow. too tired to look it up now.

I have to agree with kas83 on this one . .. A fire truck is not the place to be doing things that may possibly reduce reliability. If that engine goes BANG it could mean someone's life . . .not worth the chance.

After hearing about the stress test they put on the engine/pumps before they are shipped, any performance increases may cause problems. They have to run at full pump load for hours, who's gonna watch the gauges?

yup about '85 DDEC 1 on 92s came out. '87 series 60 introduced with DDEC 1 quickly upgraded to DDEC 2 in '88 or '89 and the '92s went out of production for road use in the mid '90s. so theres plenty of electronic 2 strokes on the road.
agreed on the nono of actually turning up a fire truck that's in service.
