510six Posted April 26, 2009 Share Posted April 26, 2009 The car has rough tune on the AEM EMS and is running on the 87 oct. fuel system until the motor is broken in. The smaller 240cc injectors definitely make a difference in idle quaility being able to maintain 14.8-14.7 in a warm idle condition. I need to sit down with my EFI guru and figure out which injector drivers from the AEM EMS should trigger the AEM injector driver and what configuration of drivers should be used ( there are "only" 10). Once the injector driver and the E85 fuel system has a "street" tune the car will get some dyno time at Church's Automotive Testing to finalise the tune. I still have to figure out if I want to plumb the nitrous before taking it to the dyno or just "street" tuning it as it is just a full throttle tune and shouldn`t be more than a 50-60 hp shot. http://home.earthlink.net/~spchurch/churchautomotivetesting/index.html http://www.aempower.com/ViewCategory.aspx?CategoryID=83 The dual 044 Bosch pumps -8 feed lines from the fuel cell to -6 lines out of the pumps into a -6 to -10 "Y" fitting then a Aeromotive -10 filter , then -10 hose to the fuel rail. The E85 fuel cell with -8 return. The E85 fuel rail is center fed by a -10 line and uses two -6 returns to the regulator. The two -6 returns from the E85 fuel rail supply two intake mounted Bosch 1600cc injectors before the regulator, which uses a -8 fuel line back to the fuel cell. That's just the E85 side of things, the nitrous hard lines should really be fun. Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted April 27, 2009 Share Posted April 27, 2009 So do you still have your two methanol injectors as well? So it would seem that you have 4 drivers left over for your 6 E85 injectors, and 2 methanol injectors. You can definitely splice 1 ecu output into 2-3 injector driver inputs. The driver box would deliver the required power to each injector. The input side of the driver box does not pull any real amperage. This is how John Reed did the AEM on RREV Motorsports methanol supra. Justin Quote Link to comment Share on other sites More sharing options...
510six Posted April 27, 2009 Author Share Posted April 27, 2009 The eight 1600cc injectors including the two on the intake tract are E85 injectors. The AEM injector driver will (probably ) use the two injector outputs for the intake tract 1600's to drive the eight E85 injectors with 4 injectors firing 180* opposed.

HowlerMonkey Posted April 30, 2009 Share Posted April 30, 2009 Any worries about washing down the cylinder walls? Never followed alcohol builds but was wondering whether you have to take the same steps as one would do in a 100% alcohol build. Very cool setup.

Never followed alcohol builds but was wondering whether you have to take the same steps as one would do in a 100% alcohol build. Very cool setup. With E85 there isn`t as much of a problem with cylinder wall washing as with a 100% methanol as 30% more fuel is typically added vs. 50% more with methanol. Care is taken with the crankcase ventilation using an aircraft style air/oil seperator (with a drain back to the pan) plumbed into a electric vacuum pump, I might plumb the outlet of the vacuum pump into a one way check valve in the exhaust, utilizing the vacuum in the exhaust.

HowlerMonkey Posted May 3, 2009 Share Posted May 3, 2009 Hmmm...........sounds very interesting. Time for me to do some research. Quote Link to comment Share on other sites More sharing options...
