Default Re: IAG TGV Delete & ID 1050X Cold Start Issue

It may need several after-start tables corrected. One of the issues based on what you describe is that the ECU is seeing an AFR fairly far off from what it's looking for and trying to correct... over-correct, back and forth.

Stock TGV's help atomize cold fuel into the cold air. Removing them will naturally make a cold start harder. If the tuner who dialed in the ID1050x's is even remotely decent, the injectors are not the problem.

Additionally, the tuner should already have an idea of the issue and fix and be able to send you maps to correct. ID1050x's, TGV deletes, and gasoline really shouldn't have this sort of issue as it doesn't take a whole lot to get right. Once you add E85 to the mix, then the work has to be put in on making it cold start nicely. It gets even more difficult when you do the KStech TGV route and leave the dividers in place... Like I have.
