#LS ECU FLASH SOFTWARE#
To clarify this a little further, let’s take a look at the software structure within the ECM. The PROM contains the calibration software for the ECM. The only difference (aside from the vehicle wiring harness pin population) was the PROM. This ECM was used on the 1989 S-10 truck with the 2.5L four cylinder, the ’89 Camaro with the 5.0L HO V8 and the ’89 Corvette with the 5.7L Tuned-Port V8 engine. For example, in 1989, Chevrolet used one engine control module, P/N 1227165, to control three different engines. The PROM chip is used to calibrate the ECM so that it is configured to run a particular engine. Naturally, this short list does not describe the entire contents of the ECM, but what is important to our understanding of flashing is the PROM part of the ECM. They have a microprocessor, built-in random access memory (RAM), signal-conditioning chips (for sensor inputs), output transistor/drivers (for actuating ignition coils and fuel injectors) and a programmable read-only memory-type chip (PROM) for calibration purposes. Going back to the basics, you know that all automotive engine and powertrain control modules (PCMs) are essentially small-sized, dedicated computers. Before we get into what it takes to flash ECMs, let’s take a closer look at what flashing really is, why it is utilized on virtually all late-model cars and why this is such a great opportunity for repair shops. In case you’re on the technological slow boat, “flashing” refers to reprogramming automotive engine control modules (ECMs). I think we can all agree that the first group is far better off, and the only thing we need to expose is the benefits of this new “flashing” technology. These repair solutions will cover more than six-million vehicles on the road today.ĭavid Hirschhorn, Director of Brand Management In a 45-minute webinar sponsored by CRP Automotive, the company that brings you Rein Automotive, we will cover six common cooling system repairs on BMW, Audi and VW vehicles. These solutions can simplify a repair and protect against future failures. These parts can create a win/win situation for your shop and customers when dealing with today’s vehicle’s complexity and longevity. Some replacement parts can be better than the original parts.
It could be hoses, plastic couplings or water pumps. Have you ever noticed many European cars and SUVs no longer have coolant replacement intervals listed in the service information? This could be due to cooling systems requiring service or component replacement prior to that interval. Sponsored By CRP Automotive, the company that brings you REIN Automotive
