What is a "Jeff O Chip"

[Slider925]

I was reading the thread on all you need to know about the MAFT translator and he speaks of a Jeff O Chip and I have never heard of it. Does anyone know what it is? Also do you have to run a seperate fuel controller with a MAFT? Thanks for the help.

A Jeff O chip is referrring to a custom eprom chip that can be socketed into your ecu if it is an eprom. Jeff is the guy who makes these custom chips, his website is www.dsmchips.com. The MAF-T is a fuel controller in itself, so you don't have to run another controller like the apexi s-afc, but you can to further dial in your air/fuel ratio. I suggest you visit that website a read about his chips, they can be a great help when running bigger injectors and let you have lots of other neat features.

I run 850's and a hacked 2g mas,idle is like factory.Runs very nice and the extended map option lets me run well over 24 psi on pump gas.
I'd suggest the stage 3 to anyone wanting properly tune larger injectors,higher boost.

They're worth every penny.The finest addition to my car,ever.

Nice thing is Jeff supports his chips 100%. Any future mod that would require a recalibration (bigger injectors, MAFT) is only $20.
