Alternate burn - still a stoich mixture in the hole but not every stroke. The main issue is the slow-ish response of the lambda sensor that will screw up the ST and LT fuel trims by enriching them to the point that it will probably use more fuel. This type of mod needs to be coded into the ECU so that the downstream effects can be allowed for or ignored as required.
