There are tuners out there who do supply OTS maps and some who offer base maps for certain cars so once again it’s a good idea to keep an eye on the tuner network. You can sometimes see example ROMs that already support different configurations in automatically downloaded ROM trough EcuTek update, however, EcuTek do not supply Off the Shelf tunes or tunes to use as a base file as we don’t have the ability to build and test all of these ROMs. The OEM ECU is set up for a very specific hardware configuration so when you come across something like a NASP car that has been fitted with forced induction or a FI car with major changes to the FI system with much larger expected performance, you may have to take into account expanding the resolution of map axis’s to allow you to accurately tune the car at the new power levels. Knowing what has been done to the car and what the client expects from the tune is the basis to good tunes, if the owner has a stock car and want a little more horse power you likely don’t have to start planning for major ROM changes. While we don’t allow reading of other tuners ROMs from ECU’s if you are to make a ROM dump we may be able to send it back to you locked so you can return to last tuned state if required. It can also be good practice (though not 100% necessary) to make a copy of the ECU if retuning so that you can return to previous tune if you find you don’t have the information to complete the tune half way through.

One other thing specific to EcuTek software is to know what CAL ID ROM is in the vehicle, this is important as some ROMs don’t have enough spare space to fit certain features in (like the newer DIT cars) sometimes you can make a good guess using a model and year but others you may need the exact Cal ID to know what options are even available to offer and sell to the customer. the Cat has been removed so you expect the P0420 codes to come on, you may not need to disable it but be ready to wen you do. This will also allow you to predict any DTC’s that might come up so that you can disable them if necessary i.e. If you don’t get this information you may find yourself trying to fix a problem that is created by to many minor or unknown modifications fighting each other. and if at all possible as much info about these changes as possible, this includes things like injector latency data, MAF housing sizes / types, MAP sensor scales and so on. exhaust, intake, injectors, turbo kit, atmo BOV etc.
As with any other sofatware you need to know what has been done to the car i.e. When starting out with a tune it important to get as much information about the car as possible before you even start the job.
