Ok, so I installed the 12v battery and can read and write just fine. I tried running the MPVI off 12 and the ECU off 16 and that didn't work. So what I figured out is the ECU does not like 16.7...
I made an Arduino program with cam and crank outputs. I entered in the timing of the 24x crank signal and cam signals. This enabled me to troubleshoot a coil that quit working when it got hot. I...
I understand that 16 is more than 12. My issue is that a read entire requires both transmit and receive functions to work properly for 2 minutes or more. A write calibration only requires transmit...
I have a fully charged 16v battery but thanks for the reply
Anyone run a 16V battery and Alternator? I upgraded to a 16V battery and charging system over the winter and now I am having issues trying to write to the ECU. I was able to read from the ECU then...
Update 5/2
Well today it wont write any more. I went to the race track and made one pass. I was lean so I tried to change some tables but nothing I tried would let me write.
I have a LS swapped 67 Camaro with a 411 ECU. Over the winter I did a lot of rewiring, and updates to the fuel system. Yesterday I went to tune from E85 to E100. Just 1 value change. I couldn't...

this is my tune. Its using the bosch 210's with 45lbs fuel pressure and is scaled 50%. I have a pure methanol injection starting at 2psi of boost. I have a 5000 Stall in a race car so...
Thanks guys, let me give you an update. I made an injector test rig using my actual fuel pump in car and the fuel rail mounted regulator lowered to 50lbs. I flowed 4 injectors at a time for 3...

Video showing decap mods to HPTuners. It says to use Static.
Decapped 903s flow 84 to 88 lb/hr
Lots of people run the Bosch 210s on gas and e85. I'm at a loss though.
Im trying to get my idle air fuel ratio leaned out on a turbo 5.3 running E85. I have managed to get a decent idle speed and it starts and runs but is really rich at Idle. This is a no O2 sensor,...
You guys really need to work on Customer Service. If things dont get better you may not be in business long.
I was at race track this weekend and up pops a box stating you must perform a firmware...
Follow up to this issue. I am running Bosch 0280158830 2200cc injectors. These injectors are heating up from engine heat and they change how much fuel is injected. I found that I was running on...
What I was meaning to post was the VE table increases linearly to 190 @ 315. I'm familiar with VE tuning but was suspicious at the need for a 20% change. This is a drag car with no way to drive...
I have read and studied several tutorials online showing how to tune the VE table to dial in AFR.
I had a 5.3L 862 heads and a LS9 cam running 7 to 8psi boost and had dialed in the AFR to give me...
Ok, if you dont mind changing to a repository tune and abandoning your tune I would go search and download 2000 Silverado 2500 LD Its a Denmah Sloppy Mechanics tune that I started with. I have a...
It gets to 5.2% read and fails, if that helps any.
I purchased a 0411 ECU from a Salvage to program as a spare for my race car and when I go to read it I get this error message. Any help is appreciated.
Thanks,
Greg

I had the exact same thing when I had a 1Bar map and 2Bar map graphing.
