I have been trying to install and Ostrich but have had no luck getting it working. Just worked out that I need an ANHU BIN and not the AUJP which is the common BIN on the Third Gen forum.

This BIN isn't listed on Moates or DIY-EFI.

Doe anyone know where I can get a copy. If not I will need to find someone with an EPROM programmer to download the BIN.

Thanks

AUJP is a '90 F-body bin
'90 Vette auto bins ANHT or ANFJ (from Moates ) should work

I tried the ANHT BIN and it does not work. Radiator electric fan runs full time and engine runs rough (but better than AUJP!). Also found another post which says it does not work. ANHW is apparently very similar but with a different rear end gear. This BIN also isn't on Moates or DIY-EFI.

I found a modified AHNU here. Pretty sure its modded to run open loop . I did not really look at it.

Send me an e-mail. I read out the ANHU prom myself, 100% stock!
With the fans running right away, you're in limp home mode.

I had huge issues with the Ostrich when first installed after fitting a Vortech V1 supercharger. The car ran extremely rich and very rough. Spent many hours trying to work out what was going on and finally worked out that the issue was radiated emmissions (probably from the MSD ignition I had installed) onto the USB cable from my laptop to the Ostrich. When I finally programmed the ostrich out of the car and re-installed it without being hooked up to my laptop the car ran fine. Basically I can't live tune while the car is running! Car now runs 1/4 mile in the 12's with an old Vortech A-trim and only 4 pound boost!

Hello,
dunno if i am right and maybe it's not nice asking as first post ?
I am looking to restore my 90 vette (hatch back, not zr 1) with auto transmission to a factory normal condition. Things to do are find original exhaust mainfolds and the original prom.
Both are hard to find.So for the prom i could try burn it myself on an eprom but i need the data to do so. You think the one you read out could fit my Vette ? and in case if u still have it are you still willing to share it ?

Not necessarily.

I have been looking at the code and it's almost impossible to get into limp mode. I have heard that disconnecting the MAF would do it -- not true. I have heard that disconnecting the O2 sensor would do it -- not true. It is not possible to get into limp mode by disconnecting sensors.

The ECM will go into limp mode when the watchdog timer times out. As far as I have been able to determine, that's the only way to get into limp mode.

You can force limp mode by connecting a 3.9K resistor across the ALDL diagnostic terminals (usually A & B). That's the way the factory tests it, which is why the FSM calls it "factory test mode".

Your are in luck, I am not that often here. I am a regular over here: http://www.corvetteforum.guru/

Send me a PM with your e-mail and I'll mail you the bin.
