I'm running a procharger d1sc with the p4 and 2 bar map. I'm wondering if it can be set up to retard timing using iat. I know there is an iat/cts blend and also a timing table for it. My question is if I change the coolant percent to zero and leave the option flag unchecked will it change the timing solely based on iat without affecting anything else?

Changing the IAT/CTS blend table also affects fueling. It is used to create the inverse temperature term of the injector PW calculation. So don't do that for SA compensation.

If your EBL P4 ECM firmware is V 1.2 there is an option flag to make the IAT/CTS based SA table, based on all IAT. If your EBL P4 ECM isn't v 1.2, download the update from our web site and update the ECM.

Then set this option flag:

Option Word 4 - Bit 4 - IatSa

And this table is completely IAT based:

SA - IAT/CTS or IAT Compensation

If you do need to update the EBL ECM, be sure to install the .msi file for the latest BINs, WUD, XDF and so on. Need to use all of the new parts included with the update.

I thought I checked for an update but must've missed it. Got it installed and tested. Works perfectly! Thanks RBob for amazing support on top of an excellent product!
