'14 Access 2TR P219A Code URD Supercharger Installed

@eon

I have a 2.7L but I will look for those ports. What do you mean by EGR?

 

blue wire sniped

 

Someone will have to correct me if I'm wrong, but from what I gather it works like this; EGR is an 'exhaust gas recirculation' system that older trucks are equipped with. So for newer trucks using the supercharger, the EGR port on the supercharger should be capped (unless you're running a 7th injector kit which I believe gets plugged into there).

 

I snipped the blue wire as well and found it to work, but takes away all ability to perform afr adjust... if you add fuel with the mapecu, and dont correct the trims with the afr adjust module, then the ecu will pull all your added fuel out via trimming... Gadget is worthless in terms of help... he simply says the afr adjust module doesnt work well with 2013+ 2trs and basically washes his hands and doesnt provide anything in the way of help... if you clip the blue wire you basically deleted the afr adjust module and your ecu will try to run at 14.7 all day long... I sold the truck anyways... im now on to a 2016 chevy colorado duramax turbo diesel

 

I agree Gadget is no help, he brushes it off his shoulder.

Do you think I should go get it professionally tuned by a specialized shop?
And is 14.7 ideal?

 

Without the AFR adjust, you will never ever get richer than 14.7.. When speaking to gadget he withheld the information until after I made my purchase... He knew what my intent was, and I was in communication with him prior to my purchase, but he doesn't say anything bad about the product until after the purchase was made and I reported back that it doesn't work. Basically then he said oh yea the AFR adjust doesn't work well with 2013+ 2tr ecus... You need tuning you will need to unplug your o2 sensor and run it in open loop.. When you do that you can tune it easily to whatever you want, but you'll have to deal with your o2 sensor fault turning on your CEL

 

Anybody know how I can adjust my AFR? I got a 15.4 right now and I think Ideal is 14.7?

 

14.7 is ideal for gasoline to burn but lean inside an engine under full load. 13:1 or so is optimal for normally aspirated engines and 11.7-8 or so for boosted applications. If yours is still 13 under full boost, you're quite lean.


But as someone else pointed out, I wonder how accurate of a reading your getting. The nest thing would be just strap it on a Dyno and check it at the exhaust. Shouldn't cost but hundred bucks or so for a couple of runs while monitoring AFRs.

 

I'm running 15.4
