Sick of the marketing spin and outright BS? Here’s 7 of the biggest ECU re-mapping myths busted! The internet is a powerful tool. It lets ideas and information flow freely from those who know theirs *%t to people who want to know theirs. It’s allowed us as a business to grow, not just in terms of reach, but the in-house knowledge we have from working with some of the biggest names in engine control systems. The downside is there’s no special license where you need to prove your credentials before passing on information. No fact-check to make sure some fly-by-night diesel tuning shop knows which end of a 4WD to put the engine before they start swaying people’s minds and talking them into costly ‘upgrades’ when there’s far better options out there. We figured it was high time we put right from wrong and start busting a lot of the myths floating around the interwebs from so called experts about ECU re-mapping and give you the straight-shooting, no-nonsense facts. Myth #1 – It’ll damage the ECU – ECU remapping has been around in petrol engines for near on 30 years now, but it’s only recently the ECUs in diesel 4WDs have been smart enough to tune them that way. The early ECUs in petrol engines were often incredibly rudimentary, meaning the people tuning them would have to crack them open, solder in patch leads and physically alter the ECU to get it to work, obviously not something you’d be keen on doing on a brand new 4WD. Modern ECUs are a lot more complicated but they’re also designed to be easily updated, just like a phone. In almost all 4WDs we’re simply able to plug into the diagnostics port, download the old program, make our changes then re-upload the new one. It does no more damage to your ECU than having the computer reset, just with a whole lot more usable power.  Myth #2 – Chips are safer than re-mapping – This is a common one lately but it’s been misrepresented. Re-mapping and chips both operate very differently. A chip alters the signals going to the ECU,
