Guys this is new to me so bare with me and ive read some of the forums on the hack itself but it does not answer this question: I need to know if I chip my p28 ecu and I want to go back to stock I just need a chip with the stock fuel map or do I remove the chip on there with the turbo map and it will go back to stock automatically?

thanks

 

Also i should add ill be adding bigger injectors 440 so if i do want to take turbo off to smog going back to stock (if i can just pull the chip off and it will reset to default) i would suspect it will run rich so does this mean i would still need to use the p28 ecu with a base map on a new chip i can pop in for the non turbo setup. OR do i completely need to remove the chipped p28 and put in the stock injectors to pass? thanks

 

Ok i spoke to someone who does this mod and they told me they solder in switches which allows me to simply switch from having the capacitors wired in and not with a flick of a switch and i won't need to even remove the chip to go back to stock. Has anyone had a similar mod where this is possible? thanks

 

From what I know, you will need a chip with the stock basemap. I'm pretty sure that you will need 240cc injectors in order to pass smog. I imagine that the guy you spoke to is talking about a piggyback chip but I can't say that I'm not wrong.

 

Well i talked to Ryan over at Church while he was relaying my question to Shaun and he said you simply install a jumper and it will go back to stock. B/c if you think about it stock does not have a chip anyway its just the base ecu. The injectors yes you are correct i would put it back to stock for sure for smog reasons.
