Here we go man. Final showdown time. Hope the boys get it sorted. Actually- I know they'll nail it- but I hope the problem is easily rectified and not something ridiculous. I'm excited to see a victory here!

car is home in the garage got it wrapped up tonight
break in tune is on it right now. Small issue though with the cjm twin pump. to keep the fuel temperature code from going off you have to put in a 2.4 ohm resistor. did that when wiring it up and it works fine but still getting that code. thinking maybe for the HR it needs a different resistor to solve this issue? going to call Charles tommorow and see what we need to change.

Hey Ace I saw that you had to do all that stuff with the CJM twin pump and decided to go a different route just using the stock fuel pump. I decided to have a 4 liter fuel surge tank made from TTG35fort's design. I'm mounting it on the under side of where the spare tire sits. There's a quick connect fitting that you can attach to the stock fuel pump housing but has a -8 output that you can send to the surge tank. I'm going to use a big Fuelab pump to push the E85 up to the motor. We can use our stock HR fuel rails and just weld in AN fittings to accommodate the bigger fuel and return lines. Fuelab also just debuted at SEMA their new fuel pressure regulator that controls their fuel pump electronically by monitoring return pressure, it looks pretty sweet and eliminates the need for a fuel pump speed controller. Let me know if you want the design for that surge tank.

ace, make sure you have the correct wires used and the correct resistance. I used 2.2k ohm because it was the closest available. I would check your resistors because there is an error rate on the one you used that could put it in an area to still throw the code.
also, if you haven't already reset the code and restart the car to try it again. The code might not have been reset and it will stay until it's reset after it's been tripped. if that's still the issue try a 2.2k ohm like i did.

yes lol, has a bad headgasget i believe so pulling the motor checking everything out. they did a sh!tty job on the install too so theres a few things that need fixing with location of the wiring and the zip tied brackets they had on it.

its a 2.4K resistor. so 2400 ohms
edit** see thats been covered. carry on.

hmm, so the cel isn't on? i wouldn't worry about it. I don't think the temp is something that causes limp mode. I thought someone who used this pump had that cel for quite a while with no issues before he used the resistor to make it go away.

it was originally. but he turned it off and it hasnt come back on yet, code is still coming up in the ecu though is what he was concerned about. shouldnt be an issue going to drive it till Saturday and bring it back up and try a 2.2k resistor like you suggested
