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...

I was never able to get the p/n working on a 7427. All of my swaps show in drive always except for the ones where i swapped in a 4l60e as well. And...

Ok thanks. I have the 68 disassembler downloaded but never used it. And I'm patiently wait for your flash kennel. Thanks for the links too. I'll...

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

I'm swapping over to Gen VI heads, milled down (but I'm not yet sure how much), a Summit K1300 cam (208/218 @ .050"), headers, dual exhaust, and an...

Are you using the '7427 to lock the 700R4 TCC? dave w

Link to Burn 2: http://static.moates.net/manuals/FlashAndBurn.pdf To read the original chip, select 27C512 (read only) with buffer address 000000...

If you mean the bootloader in the binary file you got from the BDM... The first four bytes are the initial stack pointer, and the next four bytes are...

Thanks for your response Dave, So when I read the bin file off the original chip, the chip setting should be 27SF512? And I'm guessing that should...

it's the "Range C" Input to simulate p/n, like you said, to simulate.. It used to work fine. I'm assuming so..never had to mess with it..I believe...

The '7427 does not have a P/N Switch input pin. I've read posts that hint that that there is a way to simulate a P/N Switch input using the 4L60E...

I have a 94 2500, mild modded 454, 4l80e. PCM is 6395 and 7427, they both seem to work the same. If your motor is only minor modded l would just...

with an emulator like that, you're real time tuning the bin itself which is loaded into the emulator (so just press 'save' and there's the bin)

I read that so that's why I asked. Good notes, and good points on tuning. Is the Ostrich of use for real-time tuning, then using the data to...

just so you know too... that's kind of normal, if we're talking about a large temperature variation. some ECMs do good IAT compensation and...

from ostrich faq:

fueling tables are the easiest thing you'll ever tune, even if you just do it by hand by reading your data logs. auto tuning or VE learn or whatever...

Hi Dave thanks for your response. I had read that, and havent really figured out what to do because it seems different in the maf code. but its on...

So is the Ostrich 2.0 a permanent install? Leave it in and flash as you wish? I know nothing of these devices but am intrigued. That's exactly...

The 16197427 uses a 64K chip. The Burn 2 hex addressing is 000000 - 00FFFF dave w

Also EBL will not control a 4L60/80E..... Would have to piggyback the EBL along with the 7427 to keep E-trans control. EBL supports boost. Pros and...

The EBL vs. 16197427 using an Ostrich 2.0 are equivalent (no chips), upload / download a tune with TunerPro RT. The EBL offers Auto Tuning. ...

BJDR is the one I started out with on my recent 350 4L80 build. The Open Loop AFR table is stupid rich in that table. Try looking at one from a big...

You were exactly right, I had a crappy xdf. I got the advanced xdf now. Much better. I found the open loop afr vs temperature vs vacuum table and it...

I must be using a BJDR based bin then. I also tried BNKN at one time I think.

Fascinating. How does it stack up against the EBL at that point?

One option is to use a Moates.net Ostrich 2.0 (Chip Emulator) https://www.moates.net/ostrich-20-the-new-breed-p-169.html The emulator will make...
