Ok, here's the situation. You just completed a NA to T conversion: 9.0:1 compression, T3 turbocharger, 260cc injectors, 88-89 ECCS with turbo software. With this, you realize some shortcomings with the compatibility of the software running your conversion. The 88-89 turbo software is designed to run a lower compression engine and a smaller turbocharger. You now have a higher compression engine with a slightly bigger turbocharger. Also, the low end fuel and timing maps of the turbo software do not match those of a NA tune.
So, how would YOU alter the timing and fuel maps, maybe taking the mean, median, or mode of the two, to take advantage of the low end torque provided by the higher compression as well as the higher compression under boost?
I ask, because this topic is rarely discussed. When ever something is changed on the engine that effects power, the ECCS software must be changed to take advantage of these changes. The ECCS cannot recognize that you just hooked it up to a NA block with a larger turbocharger.
This applies to any conversion that changes the mechanics of what the ECCS is programmed to control. ie., Jim Wolf tune on a NA block.
