Which way to go on 454 TBI build?

So, then do you just remove the emulator when you're done?

After "Tuning" is complete, there are two options:
1. Keep the Ostrich 2.0 installed.
2. Remove the Ostrich 2.0 and installed a chip programmed with the "Tuned" Flash (aka .bin file) downloaded from the Ostrich 2.0.

Ok, cool. Makes sense.
Those are currently backordered on Moates.net. Since I have none of this equipment, the APU1 kit seems to be an all-in-one package with a cable, emulator, programmer, etc. Would that be a good place to start? Or more specifically, would that be have all the equipment I would need for this endeavor? Minus (apparently) a memcal adapter and a ZIF.

emulators are cool but this is a pretty mild build. why not just install a zif, get a few chips and a programmer? that's how most old gm ecms are tuned. the emulator kind of goes to waste once your tune is dialed in (which like i said earlier may only take a few tries)

I have the same cam. As long as you leave the stock injectors your stock bin will run it but not well. Because of the difference in vacuum it will probably run quite rich. I just used the apu1.

Excellent. I appreciate the input. Is it fairly user-friendly?

Tuned properly I was able to lower the idle rpm by 125 and still be dead smooth. Going slowly around parking lots it is a stock feel. When you get on it there is a very noticeable difference to stock.

Then I think that's the route I will take. The APU1 package.
steveo, I appreciate you looking out for may wallet! All in all, it's not a huge extra investment to get the APU1 package vs getting everything it comes with minus the emulator, so I'll take the plunge.

Thanks, guys. This should be interesting!

Edit:
Posted before I saw your last reply davew. Buying all the rest of the equipment plus an Ostrich 2.0 seems to not make financial sense compared to the APU1. Especially if they accomplish the same tasks. I'm definitely going to try out the Trimalyzer!

Fair enough. I guess I'm just curious. Plus, I may want to put it to use in the future. I've had many OBD1 cars, mostly TBI, and will likely have more. This one is mild, but I may go wild in the future on something else.

I do not own, or have I ever used the APU1.

I own and regularly use both the Ostrich 2.0 and Burn 2.

For tuning the 16197427, I regularly use a Wide Band O2 Sensor (WBO2) and the WBO2 tuning spreadsheet posted here: http://www.gearhead-efi.com/Fuel-Inj...g)-Spreadsheet

Without a WBO2, Trimalyzer is a good tuning tool.
