Lambda issue
I have a s7 plus ecu the lambda readings fluctuate while sensor plugged in the voltage jumps around all over the place. I tried 3 sensors same results . I even pinned 6 wires direct from ecu to the sensor and same issue. Has anyone come across this issue? Could it be the ecu internal Wideband contro...

Locked cal
I have a car with a locked s7 from previous tuner. Will the ecu take a new file or will i need previous guy to unlock it first?

Flex fuel sensor issue
I parked my car with full tank of ethanol for a week, went to start it it didnt start so I plugged in laptop and saw that fuel comp was 0. So i figured my flex fuel sensor went bad and bought new ac delco sensor installed it and same issue. Under errors it says too fast. I think the ecu is getting h...

Output status when powered off
When using fuel outputs or h bridge out put controlling a relay with ground (and relay always has power) will the ecu ground the circuit when powered off? Ive had this issue on another brand ecu where when i switch ecu off the relays turns on because the ecu switches to ground when off. Im using nos...

Re: gearCutState values
nick, did you figure this out? could it be the clutch is actually slipping? I have the same issue which goes away when I lower shift rpm point. as I increase shift rpm the clearing state takes along time and shift time increase, this issue increases with rpm with me.

Re: Flex fuel sensor
Ok so i did what tim said and its working now. The input type should be set to bipolar 5v. The syvecs youtube video got me confused

Re: Flex fuel sensor
I used the same pin and installed a module that plugs into the sensor and outputs 0-5v the ecu reads the voltage. But when i remove it and use it as its supposed to outputting frequency the ecu does not read content. I also have full tank of e85 so i know for sure there ethanol in the system but the...

Flex fuel sensor
I wired a flex fuel sensor using switched 12v and chassis ground and signal to ecu i tried using both pins c13 and c32 with no luck. They wont read frequency. When i use a module that sends 0-5v it will read voltage but wiring direct to sensor it wont read. Is this something with firmware or am i mi...
