E85 sensor
Up to Link G4 Engine Management
Hi Steve.
You are correct, the E85 sensor has now been included. When you connect the 'Raw' signal to a digital input. The following information can now be used as an axis in a Fuel Adjustment table.
| · | E85 % Ethanol - this is a measure of the percentage of ethanol within the measured fuel. |
| · | E85 Temperature - this is a measure
of the fuel temperature. |
OK, cheers... thats what I was wondering - so the adjustments are basically just to scale the entire ignition and fuel maps to match the ethanol blend?
So hypothetically speaking (just plucking numbers off the top of my head) if you tuned the base map on straight 98, then set up an overlay for eth blends you could end up with a +35% fuel trim to the entire fuel table if E85 is in the tank, and the same kind of thing with ignition?
The reason I ask are for "curly" situations, such as where the shape of the base ignition tables may be influenced by the knock limitation of petrol, while on E85 the same car may be able to be mapped to MBT under the same conditions. Makes sense if there are compromises to make one size fit all, but I like to ask just in case this kind of thing has been covered and I've missed it 
Cheers
Will require a 2k2 pullup to 5 voltsHello, I have to get some things clear so I have some questions: Do you mean 2200ohm? And what flexifuel sensor is the ecu configured for? GM 12570260? How does the normal 4D axis setup look like? E85% vs Load, or E85% vs E85-temp... Thanks! Martin
