Has anyone tried the FItech 70050/70051
However the FItech harness does not come with mini timer injector harness. So you **** out of luck without adapters. Or get new injectors.
Also you must be mistaken about the MaP sensor. They are all 3 pin. LS1 and LS3 are all 3 pin.
See my pics below.
beed an IAT sensor.
no obd2 port, no SES light. It uses a unique proprietary system so all info and codes are sent through the 3.5mm plug to the handheld which is what it is used for code reading and clearing. There is no way to make it into a ObD2 port. Would be nice as then I could set up a normal scanner for datalogging. There should be a IAT plug, but you will

A.F.R stands for AIR FUEL RATIO... AKA 02 sensor. They are just abbreviating.
I think your muddying up this thread and should prob start your own thread so we can keep the "basic" questions to a minimum. Most have been covered by this point.
Got it all installed and tried to fire it up and it didn't sound good. Sounded like it was hitting on 4 cylinders and throwing codes for the IAC. The MAP sensor that came with the harness checks back to a 05 Cadillac V6. The IAC was throwing a code instantly.
The guys doing the swap and wiring called Fitech and was told that they have had problems with their harnesses on Holley TB's.
The map sensor, TB and harness was swapped out to original and the engine fired right up and ran fine.
Anyone have any ideas why the Sniper throttle body would cause problems and what that Map sensor would do. We have ordered the GM#12592525 MAP and it's on the way.

Hi
Try reloading the default software,Let me know what you find out.
Resetting to a stock calibration:
From the main menu go to the very bottom and select Write Cal To ECU. Once in this menu scroll down to the second to last selection, it should say Default v8 T195. Once on this file select it and it will download to 100 percent. After this is done it will revert to the main menu. Now go to Go EFI Initial Setup, then Engine Setup, now input all of the parameters that are needed for your application, making sure to save each one individually.
After you have entered your information and saved it go up and select Dash Board. Once in dashboard turn the ignition key off and wait for all the data to black out. Once this happens turn the ignition key to the on positon and start the car.

Here's a pic of the connecting plug.
What I find ridiculous is that FItech says you only need to run one O2 sensor, yeah right which side gets the nod. Yet when you buy the main harness with the trans controller you get the sub harness to run 2.
C'mon guys charge a few bucks more & supply both!
