Setting up WB in the ADX editor.

It's interesting you mention 2.5 Lumina. Crank sensor in the block attached to the ICM for DIS
Here is a quote from 1project2many from my first thread here.

If you were designing from stage one you could select the 7727 / 7730 ecm and use a calibration from a 91-92 Lumina 2.5 TBI to get an even later generation of ecm but since the 165 is in place I'd probably stick with that.

interesting.... the injector PW(when in async), EGR, CCP and TCC is controlled differently between lumina and S10 modes.... might explain your issues with it on.

anyways, try this out... may want to lower your fan temps to test it quicker.

included the text document of where i modified and what i changed it to.

[POZE]

Thanks Robert.
Might be a day or two until I can test it.

Well I did get to test the patch and I wish there were better news.
The fan works with or w/o the flag checked for fan operation.
It will engage at the proper enable temp but will not shut off at the programmed disable temp.
Also have the terrible throttle hesitation like before with or without the fan flag checked. WB shows way lean during the hesitation.
I listened with a stethoscope and believe it doesn't shift to asynchronous. Hmm

[RobertISaar]

guess i should have done those patches one at a time to figure out which one caused it then....

there are 9 possible culprits, could try starting with just one enabled and keep adding them in until it acts up, if you want to go through that.

[POZE]

I am good with that if you will help. The cooling fan control by the ECM was one of the objectives of the build.

[RobertISaar]

actually.... i think an easier path might be to just have the code permanantly think it's in an S10 and just write a new subroutine for the fan output. could definitely be done in less BIN revisions and cannot possibly modify anything that isn't desired to be modified.

planning on using A/C?

[POZE]

No a-c.

[RobertISaar]

want the ability for vehicle speed to turn it off?

or really, anything other than a simple "on at xxx*F, off at xxx*F" setup?

[POZE]

Let's control using on / off temperature sets only.

[RobertISaar]

since it's a discrete output, i can't impliment anything neat like the soft-start code that the 0D guys are using now, but the IAC adjustment for fan coming on should still be functional. once it's implimented, keep that flag on S10 mode.

i'll be working on this tonight... right after i eat something.

Robert what are the chances the problem is in the XDF ? I am going to try another one I have that is not as defined as what we are working with.

[EagleMark]

The one you posted is the same as one I have, Paremeter for Fan enable is also exact.

[POZE]

My mistake. This one has less defined parameters.

[EagleMark]

Fan control is still the same address...
