So how big ahve you seen or heard of a 2.0 liter type 4 with a tweeks stock FI setup???
I need to know specs, I know 2056 works, I feel that it could go bigger, I am thinking 2.2 possibly, with a higher CR and a web cam, ported/polished heads. I would like to hear Jakes real world trials to see how far he has gone, I know he has tried big displacement with the stock FI, I just want to know where the line is?? On that topic, how about 2.4 liter using the 4.8 liter mercedes injectors (they fit and have the same voltage requirements, and an old porsche race team mechanic said he had done it before) Any thoughts?

QUOTE(jkeyzer @ Oct 7 2003, 07:07 PM) I'm really surprised that to this day noone has gone into the ECU itself and changed the operating parameters inside to work with non stock configurations. We have the technology... actually, we don't. the DJet is 40-year-old ANALOG technology. the essence of the system is the way the MPS uses a variable-core transformer to shape the pulses created by the trigger points. everything else is band-aid circuitry to 'tweak' that -- cold-start, full-throttle enrichment, warmup... when you go in and start replacing bits of the analog stuff with something you can actually get parts for, digital stuff, to replace different elements of the pulse-forming and pulse-shaping modules - you will find that you have re-engineered the MegaSquirt (or one of its ilk). |
