Engine shutting off under wot

[gOt BoOsT]

Hey guys ive been having a weird issue the last few times out this season...under prolonged wot the engine will just die without any codes. short wot bursts are fine, but hold it for 5 seconds or so and it dies. starts right back up before you even come to a stop like nothing ever happened.

ive changed the plugs, cleaned the injectors, put a gallon of 91 in the tank of e85 and just added lucas ethanol treatment to this tank. i need to wire in a relay for my 340lph areomotive, but ive never had an issue and have ran it this way for two seasons.

any ideas or input is appreciated

You shouldn't be running E85 In A stock setup. What type of motor do you have?

[hotbird]

he has a jaws turbo and its tuned for e85

[hotbird]

do you have the capability to data log whats going on?

may sound silly but is the key staying on tight at speed? If they loose connection they will just quite making you think something happened.. typically when we like to stretch out on seat. Squeeze the end of key to make it fit tighter on dess post ... Hope it's that simple

I had the same symptoms when I had the V-Tech tune. Are you using one?

[imp0ster]

I'd check for over amperage

Install the relay to run the aeromotive. I think that is your problem
