higher.
That is correct, that is a GM number. That is why I said what I did about 128 blm. It only means at that point, wherever the afr is, there be little comping (of course depending on what one is seeing w/the int.) Most seem to believe that a 128/128-126int. tune is 14.7. Yes idle should be the worst of all evils, particuallry if there is a lot of overlap (02 "seeing"02).
I also found that with my own different set-ups 14.7 isn't were the motor liked it. The swing points are reflected in both upper and lower thresholds in the 727ecm. (idle 02 and upper vs. MAP), and have direct relationship to the AFR. In a stock bin the crossover/swing points become raised in the upper kpa. Tunes I have seen from a couple known guys have put the 'crossover' the same as idle. There are a lot of ways to get there.......in those tunes, fuel was added in many other areas of the tune.
On mine I am using the moates piece that the LM (apad a/d),through the apu-1, as a permanent fixture in the car. I have the other typical stuff as well, lm w/rpm etc.etc.

I see you're having fun too...lol
Tuner pro rt is great for tuning as you go, truthfully I think the
tuner cat might be better software though. The problem I see is that when comparing all of my software, they all shows slightly different numbers (TTS, Tuner proRT, , Tuner cat)....probelm is out of all of it you gotta believe in one of them. I got the dependability improved w/the tuner pro rt/apu-1 when I made a new cable (instead of the ribbon one supplied)from the ecm, chip socket booster etc.

The Tuner Pro RT or Tuner Cat I would be using to write to the Ostrich which I will permanently install and run the car off of. The Bluetooth connectivity is really cool.

I'll use scanner pro or may have to get the TTS. Two different things.

I don't have the ADX. I am going to try it on Saturday. I never used it. How do I get the ADX?

this is all new to me Jeff, be kind. I'm learning.

I agree it is cool, I have had the blue tooth peice sitting here for awhile, never used it. I was getting a lot of cable interference, and too busy sorting that out while using RT.
About 2 years ago I installed a 6al, and that's when I started getiting all the problems.

I'm using 8D with the EV tables and pulse cap eliminator.

Okay..

to change the BIN file in TunerPro you need the XDF. so for you you need a XDF corrected for your extended VE tables

for Scanner Pro you need an ADX file that will match to the ALDL Stream.

I assume you already have the OBD1 cable to connect for datalogging with Scanner Pro.

with our cars you need a few pieces, the Ostrich will hand the BIN file, but you need the OBD cable for the logging portion

Also I am not sure how well the Bluetooth will work with the Ostrich being under the hood..

I have the cable from OBD1 to USB with a jumper set for a resistor. I understand I don't need the resistor on the 90 I am told.

I do need the logging portion. I know that. I didn't realize I needed an ADX.

Get everything first, then we will know what you have and what you might need

Here's what I will have as of Saturday:
1. Bluetooth Ostrich and required cables, chips, and connectors.
2. Tuner Pro RT
3. Tuner Cat Haven't decided which to use
4. Bluetooth laptop, have it now
5. Scanner Pro
6. Cable from OBDI to USB with jumper for resistor

What else will I need? I can easily physically hood everything up.

So, in a 727, are the O2 swing points based on kPa or airflow?
Are you saying that your WB O2 output is running through the Moates APU-1 or is it wired directly thru the ECM? I'm still a bit unclear.



jsup,

One of the differences between TP and TC is that TC has had a limit of 99 parameters. TPRT has the editor built into it while its a separate utility for TC.
I have used both and prefer TPRT. That's JMO.

I think what I am going to do is to with TCAT for now, and work with my tuner as I learn more. This will keep things consistent between us.

Once the tune is done, I'll switch to TPRT.

Is there any disadvantage to that?

That's how I started. Up to you. However, there should be no discrepancy between using TC and TP. The parameters will be the same as will the values.
After that it becomes a matter of preference. Knock yourself out.
