I need to find out injector size so Yoshi can program the MID. As I said, TeamSwift keeps locking my system and it's ticking me off.

MetroMPG, anyone, please help? Please?

Both IE6 and Netscape 7. I think it actually has something to do with the server in my workplace. Possibly Norton's remote scanning or something. Teamswift is the only site it happens on and only after I surf through 4 to 5 pages. It's weird.

I'd do it at home, but my computer is in pieces at the moment (and I'm sick of computers by the end of the day) and my wife and kids are always on theirs...

Looking through my last SuperMID Revisited post, I said I had found a number of 272 cc/min on Teamswift. However, on my latest visit before my latest lock up I found out that the 272 cc/min is either not correct or only for Swift GTs.

I don't know. I'm confused about the whole thing.

OK, tell me exactly what you need to know, and I'll look for it or post a question. I think all the 1.0 and 1.3 motors are TBI, not multi-port. I'm not sure if that changes things for you.

Keep in mind I also know nothing about injectors...

Me neither , all I know is that Yoshi asked this question:

Quote:
In the meantime, would you please check the specification(xx cc/min) of the injector on your 3 cylinder Metro?
So I just need to know how many cc/min the stock 3-cylinder TBI injector spits out.

I was thinking that I should see if any of the Suzuki/Pontiac/Chevy parts people would know as well. They may have it in their computers. I'll phone or visit some dealerships later today.

Wait a minute...I just found a site with the formula for converting cc/min to gal/hr and it suddenly clicked that you listed your liters/hr in your warm-up time experiment.

0.5 Lph was your warmed up flow and the initial start flow was 1.5 Lph, so this calculates to:

500cc/h = 8.3333 cc/min at idle.
1500cc/h = 25 cc/min initial start.

These values seem very small. So how do they calculate/measure fuel injector size? Maybe it's what the injector is capable of flowing. More to figure out...

EDIT: Interesting...I just punched 65 hp and 1 injector into the calculator here: http://www.rceng.com/technical.htm and it gave me a cc/min rating of 272...coincidence???

Sorry I miss the importance of the 272 in the coincidence

EDIT: OK, I see it's the number you found at teamswift previously.

Then again, our cars make 55 hp peak, not 65, so that calc may be off.

Also, doesn't nn cc/min depend on RPM and load?

I wonder if Dan has anything to offer. I didn't pay much attention to the injector discussion he was having with Ben, when they were calibrating their MIDs.

Oh, 272 cc/min was a number I found on Teamswift, but some guys were saying it was wrong and others were saying it was just for the GT.

I assume it would depend on load, but I figure that this must be the maximum rating - perhaps at wide open throttle. Ben was saying that the VX injectors were 190 cc/min or something like that.

EDIT: oops...55 hp, right. I don't know why I always say 65. I guess I'm hoping for more?

EDIT2: Injectors are rated at 100% duty cycle, but only operated at 80% maximum.
