If it is a match to original the you are done! You can write the file into the chip now. Now write 00’s instead of FF’s in the highlighted place. How to Make Checksums for ECU Files with WinOLS Pic. Highlight FF’s and do the checksum till you get right value 17E8 Now when you know where correction must be done, go into HxD. Correction must be done in darker places with FF’s Pic. You need to calculate the difernce between those two checksums. Open your calculator and set on scientific and on hex Pic. Tuned file’s checksum must mach to original file’s checksum. My original file has 71A4 checksum and my tuned file has 898C checksum. Now load your tuned file and do the same Pic. 11 HxD checksum menuĬheck out the result Pic. 10 Hxd menuĬhoose Checksum-16 and press OK Pic. Open HxD and load your original bin file. Here they are:īefore writing the bin file into the chip you need to correct the checksum. Since I wrote this file using the 175 computer from a BMW e30 318is with softwareĢ14 I found almost all usefull maps. Also in that case using fuel with the highest possible octane number is If you change this map I suggest adding not more than 10% ignition advantage. The factor for RPM is 40, and the offset 0. The Ignition at WOT is 1×16 and looks like this Pic. When you “over tune” this map it will result in damage to the engine.įor proper tuning knock-detection equipment is needed. If you change this map I suggest adding not more than 10% Low part throttle map is 6×12 and looks like this Pic. High part throttle is 7×12 and looks like this Pic. Ignition at part throttle just like in injection at part throttle, is two maps: high part and low part throttle. To change this map in a good way you need a wideband lambda sensor (or a dyno) to achieve the proper Air Fuel Ratio (AFR). Just like the closed and part throttle maps. The values are the correction-values for the, by the ECU, calculated injection pulse length. The injection map does not have absolute values in it. The Injection at WOT is a 1×16 map which looks like this Pic. Low part throttle is 6×12 and looks like this Pic. High part throttle is 7×12 map and looks like this Pic.
Bosch ecu tuning software and hardware software#
We will keep our news feed up to date with the release of custom TVS software for the new Bosch MG1 / MD1 models.In M1.7 are two tipes of maps: High part and low part throttle. VAG engines for which TVS custom ECU software is available soon: Engine As always, our goal is to achieve the perfect balance between maximum performance, drivability and durability! Our development program includes hours of dyno testing, street measurements and analyzing data. While the factory software was already available in some cases, proper testing, analyzing and developing software takes more time! Therefore we strongly recommend not to rush now to get a tune!ĭirectly after the release we at TVS started our development program with new development cars. Shortly after this release a lot of tuning companies directly started offering tunes for these models. TVS MG1 / MD1 ECU software now available!įrom now on it possible to reprogram the new Bosch MG1 and MD1 ECU’s! These can be found in the latest 1.5, 2.0, 2.9 & 3.0 TSI & TDI VAG vehicles.
