A set of firmware for the car LADA GRANTA with engine 21127 (106 hp) 1.6L 16V and robotic 5-step. Gear box AMT 2182
Equipped with control unit M74 "NPP ITELMA" 21127-1411020-62, 21127-1411020-63 for installation instead of firmware I474GF04, I474MKA1
In the complete set of the firmware:
I474MKA1 E-2_ori (firmware will not change the performance characteristics of the car, but it will save some of these problems)
The firmware with the disabled diagnostics of the neutralizer and the diagnostic oxygen sensor (DK-2), the other parameters are factory-set.
The firmware is suitable for those who are satisfied with all the running characteristics of the car.
But because of low-quality gasoline in the region of residence constantly annoying engine errors "Low catalyst efficiency"
(Eg P0422, P0421 - The catalyst efficiency is below the allowable threshold)
Or after forcing deep puddles on the roads there are engine malfunctions:
P0036 Oxygen sensor after neutralizer, heater circuit breakage checked
P0037 Oxygen sensor after neutralizer, check the short circuit of the heater circuit to ground P0038 The oxygen sensor after the neutralizer, check the short circuit of the heater circuit on the bore
P0136 Oxygen sensor after neutralizer, open circuit signal
P0137 Oxygen sensor after neutralizer, low signal level
P0138 Oxygen sensor after neutralizer, high signal level
P0140 Oxygen sensor after neutralizer, open circuit signal
P0141 The oxygen sensor after the neutralizer, the heater is defective
P2270 The oxygen sensor after the neutralizer, no response to the enrichment of the mixture
P2271 Oxygen sensor after neutralizer, no response to lean mixture
I474MKA1 TUN (firmware for those who want to improve the running characteristics of the car by minimal means)
Firmware with optimized running characteristics without changes in environmental standards.
For regions with high-quality fuel. Visibly improves the dynamics of the car, especially with the air conditioning turned on.
With it, you need only use high-quality gasoline to avoid detonation.
I474MKA1 E-2 + TUN (firmware for those who decided to do tuning their car by upgrading the intake and exhaust system)
Firmware for use when installing the initial tuning package on the car.
For example, the package "Stage 1" which includes:
Air filter of zero resistance,
Inlet duct and intake manifold of reduced resistance,
Without catalytic exhaust system.
