I am planning to do that but you have to set up the air fuel ratio meters on a separate battery supply to see the first few seconds of the air/fuel ratio as the start up interferes with the meters on startup.

I will wait till its about 5 deg mornings in Perth before I start doing this.

From a Delphi website:

  • Ask about improper E85 usage.

    Although all modern vehicles now run off of fuel that contains some ethanol, E85 is not compatible for the vast majority of today’s vehicle market. With prices that are typically lower than gasoline, drivers often fill up on this cheaper alternative without realizing or considering the damage it may do to their vehicle. Essentially all alcohol, E85 is a drying substance and is very hard on fuel pumps and seals when used in vehicles not designed for E85 fuel, and can lead to serious malfunction. Premature failure, fewer MPG and reduced power could be indicators of improper ethanol use, signaling that a repair needs to be done. Be sure to ask the customer with these symptoms if they have recently used E85. Without proper diagnosis, this can result in unnecessary comebacks if the E85 use continues.

  • Check fuel level – and make sure your customer does too.

    Most people have driven on empty plenty of times without a second thought. But, driving on “E” can contribute to fuel pump malfunctions. It’s your job to make sure your customers know why. Fuel cools the pump motor, so when drivers are running on little to no gas, overheating can result. Besides heat damage, running a vehicle on low fuel causes the pump to pull the dirtiest fuel from the bottom of the tank and possibly cause increased wear. This can destroy or shorten the life of an electric pump. Unfortunately, there are no visual indicators of overheating. A pump in this condition can only be identified by performing an electrical check. It will either be bound, not turning, or show as an open circuit. Overheating will cause it to fail.

Mine is cranking fine in sub 10 degrees C. No different to hot start....even with the cams. I'm at ~0.6X lambda. I'm still using a 0.8mm gap, 6 rated plug.

What J did note was that when my fuel relay sh*t itself and was running off the intank the cranking was quite delayed.

FYI.....excessive crank / delayed fire is quite common with just intank Walbro running. I'm talking on PULP too. When I first got my car tuned by XFT and a Walbro intank was fitted, the first thing I noticed was that it took several more cranks to fire.

I had to do the same thing. Instead of configuring my wideband that is permanantly mounted in the car to run to constant power, I just used the LM-2 with a female 12V socket to Alligator clamp adapter.
