Here are some logs of cars that have been measured on the dyno to get a idea of the different timing charts.
IS20 on E85 mix: 270whp Mustang with around 340 torque.
IS20 on E85 mix: record run
Will get the dyno runs of this car to see which low boost setting he used for the 290whp.
On the VW JB4 I Avg is a internal figure and does not relate to timing so we only looking a Ign1 and keeping that curve healthy. The value will fluctuate based on IAT and if the "stock boost" the ECU is seeing is approaching the programmed torque limit. In some cases it will dip the Timing.
At high rpm the IS20 is still efficient at 18-20psi so you can off set timing for boost. Higher than this 1psi will give less power than a degree of timing.
Because the ECU is so advanced in terms of timing control we decided to intervene with its timing control. Once there are fuel upgrades available to supply higher E85 content (the rear low pressure fuel pump is the limiting factor) we will look at a add on to jack the timing up at high rpm.
These high numbers are obviously in the realm of the unknown in terms of reliability for the motor and transmission so we breaking new ground here.
