That's going to be awesome. You keep this up and you ARE going to end up with the LeMans X5 sound/feel.

Is it going to require additional tuning? I think you said you are using a DME that is a one-off type thing.

So I have 3 types of electronics in my E53. DME, E85 ECM, and a secondary injection ECM. The BMW Doctor states that, the collectors as he calls them, provide more power based on the rearrangement of the exhaust gas discharge dynamics.

It makes sense, make more power by making things more efficient. My 2 Stroke with a carb, made waaay more power with a chamber that was extremely tuned!

So, where I luck out is, my E85 ECM is constantly tuning in real-time. Itís a byproduct of the system, because itís an actual Flex-Fuel system. So if there is E10, E50, E85, E100, etc. it has to tune accordingly. So far the DME has been consistent at throwing timing at the system.

So, if the head is running cooler with the ethanol, and the exhaust discharge is creating a cooler environment as well with less heat and pressure, then one can assume the DME will throw more timing. Where the end is at, is anyones guess.

One thing I can say is, my boost should be greatly affected in a positive way. My blower will no longer be blowing directly into the cats. This should allow it to produce boost more quickly and efficiently, and may even allow the pressure to rise a minuscule amount. Iíve seen it hit 11lbs before. If it were to get closer to 12lbs, that would be in my opinion the most boost acceptable on stock internals. Itís right there!

We will see soon!

Lord I wish I could do this but alas in CA I wouldn't pass emissions anymore. Now any ECU tuning will make it impossible to pass a smog...much less a cat delete. I will have to live vicariously through you!
