Message: [QUOTE="Sixfoh, post: 1558107, member: 32072"] Hey guys, sorry i didnt respond sooner. The dual fueler kit is through the vendor you mentioned. I have asked who they recommend for dialing it in and there is no response via email, ill need to call. But i believe they avoided this question in the past to some extent. What i do remember is their theory behind the kit is that the factory mounted K16 will self regulate the pressure and volume of both pumps. Since the cp3 is not electrically controlled in this application, (older attempts have failed using other electrical connections for controlling), it runs at full fuel and the metering of fuel is left solely up to the K16. I will say this is possible and has been how my truck has been running for two years very well. I wouldnt slam the driveability as it only has issues in unique circumstance, you can find this in my other threads. Whats funny is the programming i run most of the time has a parameter for dual fueler with the K16/CP3 setup. It works well as ive mentioned. However ive also run files without this parameter present, computer assuming one K16 is responsible for high pressure fuel and these work almost just as well. This sort of validates the vendors theory about the factory mounted K16 being able to self regulate the pair. Where im at is, i have a great base file that is almost 100 percent perfect in terms of driveability, but could use minor refinements. I would also like to build a file to maximize performance on track day. As well as a file with good power and safety parameters for towing. Perhaps even an economy setting might be useful too. The former two being my highest priority. [/QUOTE]
