intern8tion9l Posted February 10, 2006 Report Share Posted February 10, 2006 i was wondering if its possible to dyno tune these engines for a/f. i know some cars require crazy modifier things in order for you to be able to change the a/f, and i was hoping these aren't the same way. an insight would be appreciated Quote Link to comment Share on other sites More sharing options...

DaveFromColorado Posted February 10, 2006 Report Share Posted February 10, 2006 most Dyno's have wide-band O2's and log everything including A/F ratios. Yes, you can tune these, but you will need some aftermarket device to make it happen, either burning your own chip, or using an aftermarket a/f modifier like an SAFC or something. --Dave.

DaveFromColorado Posted February 10, 2006 Report Share Posted February 10, 2006 hey, I didn't even think about an adjustable pressure regulator... that'd be perfect! the dyno's that I've worked with don't datalog everything in the motor, but they'll watch RPM vs. A/F ratios so it's moderiate logging. --Dave.

dbtk2 Posted February 10, 2006 Report Share Posted February 10, 2006 what do you have for mods on your car? (just wondering why you want a dyno tune) Shawn Quote Link to comment Share on other sites More sharing options...
mfewtrail Posted February 10, 2006 Report Share Posted February 10, 2006 Pretty sure he swapped(or is swapping?) a TGP engine/setup into his Cutlass. Quote Link to comment Share on other sites More sharing options...
intern8tion9l Posted February 11, 2006 Author Report Share Posted February 11, 2006 yeah i've got the 3.1 turbo out of a TGP. it is chipped with a bunch of other stuff too(i'll give everyone pics and mod list when its complete). just was wondering how beneficial a tune would be and also if its really needed Quote Link to comment Share on other sites More sharing options...
DaveFromColorado Posted February 11, 2006 Report Share Posted February 11, 2006 Dyno tuning a performance engine like that is certinally needed. Period. you start modifying an engine, you'll want to make sure your a/f ratios, and timing events work well together so you don't end up burning down pistons or watching rods misplace themselves into the block. --Dave.

intern8tion9l Posted February 13, 2006 Author Report Share Posted February 13, 2006 well i'd def like to tune it, but if i have to get a whole lot of expensive crap chances are it'll have to wait unfortunately Quote Link to comment Share on other sites More sharing options...
DaveFromColorado Posted February 13, 2006 Report Share Posted February 13, 2006 I'm sure you can go out there, get a baseline run so you can at least see what your current settings are, and then work with someone who burns chips to see what you can come up with. if may not be as expensive as you're thinking, just way more time consuming. --Dave.
