EGR removal tune?

[90c350]

Tuning a freinds truck with tuner Pro rt.. Its a 1996 GM 1500 4x4 and Im using the Advanced $0d xdf and its a 7427 BJYL bin etc.. He has recently removed the egr and I would like to know what parameters/Flags etc to turn off or modify? Appreciate the help guys its been a few years since ive tuned a TBI system. Thanks again..

Oh and for some reason I cannot get tunerpro RT to connect to the ecm to datalog? It does recognize the cable and I have the right usb port etc. But it wont connect? Any help would be greatly appreciated!

I'm confused 1996 is OBD II? To delete the EGR, I set the minimum temperature to enable EGR to Maximum, 151 C.

1996 truck but it would be a late model 1995 etc.

There were no crossover models ... it's either an OBD-I 1995, or an OBD-II 1996. Take a look under the hood at the top of driver side inner fender ... if there is a black box PCM with 4 plugs in it, then it is a 1996 OBD-II vehicle.

Ive already stated that its a 7427 ecm.. That would mean that it is OBD-1 etc.. But it is registerd as a 1996 truck. IF it was OBD2 it would be the 0411 ecm etc.. Thanks guys.. Any help on the tune and flags parameters that I need to adjust and turn off? Thanks again

I think the attached screen shot will help? This is how I disable the EGR. The screen shot shows the compare feature of TunerPro, which show a stock .bin setting for EGR.

Setting the minimum speed for EGR to 255 MPH is a good plan also.

I like using the parameter finder tool in TunerPro.

Wrong again, it would not be an 0411 PCM.

There's no way to register a 1995 truck as a 1996 MY truck! Unless it was stolen and had VIN plates swapped?

You should update to the latest version of TunerPro if you want the new $0D files to work!

With EGR off none of the EGR fueling or timing tables will be enabled.

I'm wondering what setting are in the Preferences?

From the TunerPro tool bar:
Tools
Preferences
Data Acq/Emulation

Thats a great Help thanks Davew.. Is that all that is needed for egr off though? With these settings will I not have to change the egr fueling and timing settings?? THanks again and I will try the setting to get the datatlog to connect. Appreciate it!!!!

I must be using an Older version of tuner pro? Version 4.14 ? You screen shot has different preferences than mine? Oh well ill mess around with the settings and see if I can get a connection. My interface types are Max 232-2/ 2Trans/ap or autoprom or translator pro? And Im using the ALDL1 and cable1 for the obd connection.
