Literally the best and reliable way to build a Supra is in this Chanel proven combo that’s streetable, powerful, reliable, just need a infinity, m1, or haltech then it’s good to go. It will last forever like this.
@@TunerTestDrive Sweet I picked up a mapecu3 at that start of the year and was wondering how far it could go. Love the car man looks like a blast to drive.
Just be careful with the Map Ecu, it may just be a piggyback but you can destroy you engine if you don’t know what you are doing with it. If you are “tuning” yourself just read up so you have a pretty good idea of what you are doing or trying to do with it.
@@WhoGoesDeer One of the initial hurdles is getting a base map that will allow your car to start and idle well enough to start tuning. Once you have a map where the car stays on and doesn't die you can put the ecu in "follow me" mode which allows you to add/subtract fuel in real time as you drive. You'll need to watch your AFRs and add/substract fuel as you drive around. Doing that will give the basic fuel map shape that you can then smooth out and refine as you get the AFRs closer and closer to your targets. Hopefully you are OBD1, so you can unplug both O2 sensors and run in open loop all the time. This will prevent the ecu from trying to trim your fuel and fight the fuel map you have "tuned". I'd advise against any high boost tuning on the street because its hard to watch AFRs/boost level and the road at the same time. You'll want a nice fat fuel map for any in boost tuning then trim it back after each pull. I got my map on 17-18 psi pretty well dialed in on the street then just extrapolated that when I was on the dyno to go up to 29-30psi.
