As far as the throttle body, are you talking about the Holly 670 cfm or are you talking about a bored out stock unit? What is involved and what are the advantages to upgrading the computer?

The Holley Throttle Body is one of the 670 CFM options, the other 670 CFM Throttle Body option is the Big Block Chevy 454 Throttle Body.

The 93 ~ 95 TBI computer with Red / Blue connectors is 8192 Baud / 64K PROM. The early TBI computer is 160 Baud / 4K PROM. The 93 ~ 95 TBI computer with Red / Blue connectors is about 51.2 times faster and the PROM has 16 times more memory.

Don't tell anyone about the Red / Blue TBI computer, prices might increase. The Red / Blue TBI computer is the secret to an AWESOME TBI system!

Thanks Dave. Here is a computer I found on ebay: http://m.ebay.com/itm/391042139144?nav=SEARCH
Does this look like a good deal?

Seems a touch on the high side for price, considering it's supposed to be a 350 Memcal and you don't have to waste time searching a salvage yard to pull one from, it's still a fair price.

Thanks for everything so far guys. I have continued my research and played with TunerproRT, and I think I can do this. I ordered my Vortec crate motor over the weekend and it should be in tomorrow. Next thing on my list is tuning equipment. I think I'm going to order the APU1 AutoProm package, a G1 adapter and S2 ZIF. Does this sound like the right combo for the 427 ECM I'm going to get?

[dave w]

My personal choice would the Ostrich 2.0 emulator, which eliminates the need for a chip! The emulator allows updating the .bin file, even with the engine running.

I must be confused. So, if I buy the Ostrich 2.0, wouldn't I still need a chip burner/reader so I can drive without my laptop once I get it tuned right? According to Moates.net the "APU1 AutoProm package" is an all-in-one burner/reader, datalogger, emulator that comes with Emulator cable, ALDL cable and 2 chips. Does the Ostrich 2.0 have a better emulator function than the APU1?

[dave w]

I like the lower price of the Ostrich 2.0, which only emulates. If you plan to tune several vehicles, than the added cost of the APU1 makes more $en$e.

I've helped with several remote tunes. After the tuning was finished, the Ostrich 2.0 was removed and a "burned chip" was installed for the long term.

Making progress, ordered my Ostrich 2.0, and G1 adapter, then after work I found this at Pick N Pull today for $28, with a 6 month warranty.

[dave w]

That seems to be very good deal. The BJYK Memcal, based on the information available to me, is from a 1995 5.7 Liter / Automatic Trans.

I was not looking forward to repining my stock wiring harness for the 427 PCM, so instead I made an adapter with the plug from my old ECM. If anyone sees a reason this won't work, let me know. The only question I have is in regards to Pins E14 (MAP Reference/5 volt Ref) and F14 (TP Reference/5 volt Ref) which according to the pin out spreadsheet both go to Pin C14. There aren't any notes about it and the chart with color codes shows pin C14 going to pin E14 only, it doesn't mention F14. I soldered both wires to pin C14, am I going to fry something by doing this?

[fastacton]

I think there are a few of us that have made similar adapters with good results. I've got E14 to C14 and nothing to F14. I don't think you'll fry anything hooking up both, but there's not a need to.

Your Pick-n-Pull has much better deals than the ones I go to! That would be around $60 out the door with a 30 day warranty around here.

I believe she rang it up wrong, then she saw the wiring after I had paid and said, "Oh well". And the 6 month warranty kinda blew my mind, so I was very excited to get it out the door for $28, plus it looks perfect inside with no signs of corrosion. If F14 is not needed, I will disconnect it just to be safe, thank you.

Adapters are a good way to go, at least for testing and proofing. I've made several adapters over the years for various applications. '7747 to '7730/7749, '7148 to '7730/'7749, '7730/'7749 to '7165 and a couple others. I'll be making a couple more this summer to go between the current harness and a couple aftermarket ECMs.

I'm pretty sure there's another thread (or two) floating around with other people's adapter harnesses, but here is one I started, that shows the use of some DB computer connector pins that works far better than soldering the wire straight to the pin of the donor connector. http://www.gearhead-efi.com/Fuel-Inj...ne-or-started&
