What can a dyno w/ wideband O2 do for a stock FD?
I've done the simple mods, (downpipe, y-pipe) and my intake /exhaust is stock. I might add a K&N and hack my airbox for CAI.
I plan to pay attention to the A/F ratios and power curves. Is there anything else worth mentioning? Is there any 'tuning' that can be done with stock ECU and turbo setup? Would this help me diagnose my occasional 11-12 psi boost spike (post-transition) and low transition (5-6 psi)? Dave |
It can show you your rwhp and A/F ratios.
That's about it. Since you are using the stock ECU, it's not like there will be any tuning that can happen. |
thx champ.

And its not stock if you've done mods. ;)

A dyno would be worthless to you right now with the exception of knowing how much power you're making. Unless you get a standalone or some sort of piggyback you aren't going to have anything to tune.

There is nothing you can do to the stock ECU. I agree with Kyle, a dyno would be a waist of money for you at this point. A dyno and a wideband are used to creat fuel maps for aftermarket engine management systems and/or fuel computers.
It will not help you diagnose your boost problem. |
The main benefit is it will let you know how much headroom you have in terms of mods before needing to upgrade the ECU. Stock ECUs run pretty rich so if you dyno it and you're still in the 10s on the A/F ratio, then that gives you some peace of mind. I'd also fix the boost issues before upgrading the ECU.
