On stock computer car utilizing a chip(eprom) this is an area that can make the transition into AI(alcohol injection) easy or hard. The issue stems from adding an additional injector on the motor(alcohol) and having the fuel/timing tables setup to compliment this. Typically most street chips will work with AI. Examples are the Thrasher 92, Reds 93, Lubrant 93, etc.. These chips typically state a PSI. Ie 17 PSI. What this means is at WOT the injector duty cycle programmed into the chip will only deliver enough fuel for lets say 17 PSI. Now you throw an alcohol kit on the car and run 22 PSI. The extra 5 psi worth of fueling came from the AI system. For the longest of time my back-up chip was a thrasher92 in the process of experimenting with different chips and AI. I would always count on that chip in case of any weirdness.

Now fast forward technology a little. My current favorites are the TurboTweak chip for alky, the Extender, and the Max-Effort.

The alky designation now means we'll throw in additional timing in lower gears, reduce timing in higher gears, expect a reduction in fueling to compliment the AI, and allow flexibility in tuning the parameters within the chip to "tweak" its operation with the motor.

While I have lots of experience playing with the Turbo Tweak and Max-Effort, I have used with success the Extender as have lots of my customers.

I dont want to say someone else's chip will not work, this is a fine line, but want to express what I have found has worked seemless for me. For a simple plug-play chip.. the turbotweak chip on installs I have done.. has made the transition seemless.

Just to note, my vehicle currently supports the Max-Effort ME-r

So you got a chip... what next.. unplug the connector by the battery, put the chip in, plug in the connector, set the fuel pressure per chip makers recomendation.. drive the car and let it learn the new chip.. go to the above post.. and follow through the numbers on it. If the drivablity is ok.. install the AI system, and start the tuning process.
