How have your been adjusting the calibration for years without logging anything? Rightly or wrongly - yes. I have used the wideband on long steady hills in different gears and different loads to get the VE chart set. I usually do this with the laptop on the passenger seat. Other adjustments i have ...

Sorry I thought you were considering running a '165, not already on it. It sounds like you have a wideband connected. Can you post a log of something like a 10 minute drive, better if it has stalled or almost stalled on decel? Yes I have the whole setup and I'm happy with how it works. I willpost a...

What sort of issues do you have with how it runs It actually runs well, but its not like a stock tune so it has some quirks. First, Antus- I did do the math for the injectors and they are set up well. I forget how I connected to the Northstar crank sensors (there are two) but I did use them, and I ...

I was afraid of that - the Northstar is a nice engine, but a bit of an albatross - not much else like it. I guess the 12P I started with was also meant for pushrod V8 - its what was with the OSE12P setup from the start. How much different would variables pertaining to defco, a/c intergration, knock ...

Here's my Bin. The engine runs well on it, but it's not perfect. Caddi Northstar OSE12P.bin EDIT: updated the BIN. The prior one had the incorrect WBO2 sensor voltage thresholds. Thanks for having a look. Perhaps one of the stock bins listed by Delcowizzid on https://pcmhacking.net/forums/viewtopic....

Further to my last post..

Am I the only one running a 7165 and OSE12P on a Northstar?
Every so often I do a search for others for additional info or ideas and get no response.
Anyone else doing this?

Cheers.

I run a Vin Y N* in my Fiero. I use a 7165 ECM with OSE12P for engine only operation - I have a 5 spd. It runs well, still have minor issues with some aspects of the tune, mostly around idle and integration of A/C, cooling fan etc. Major tuning of the fuel map is quite easy with the WB O2 sensor.

That would make the knock frequencies around 6.14kHz and 6.10kHz - should be close enough to give decent results.

Picked up a new 305 ESC unit today. I'll see how well it works on the Northstar.....
Thanks guys!
