Aquamist HFS-3 and MINI Tank GB

From what we've seen on other DI cars with Lambda feedback control, you can almost dump meth at will and the ECU will compensate, until it chucks a code. You will use more, but that's up to you. The important consideration is using the failsafe correctly if you have a hiccup.

The jets were supplied based on the range of fluids and range of HP levels expected from these cars. Not having seen numerous data logs from multiple cars I can't give an exact answer as to the perfect jetting for each application.

One simple way to look at the jetting issue, is run the 100% and .8mm jet, log IAT, knock and the like, then switch to the .7mm and see if anything changes for the worse. If not, then the smaller is fine.
