1. about electrostatics in basic physics back in high school or earlier and we observe ESD on a gigantic scale when lightning strikes occur during thunderstorms About 5 10 years ago the major cause of IC integrated circuit failures was Electrical Over Stress EOS which results in gross damage to the internal metallic structure of the integrated eircuit s If electrical devices are not handled properly you might damage them by giving it small lightning eventhough you do not notice anything or can see any physical damage Therefore it is recommended that use professional person in order to upgrade your chip If you want to do it by yourself follow the instructions so you do not them harm the PCB Chip upgrade procedure 1 Be sure that you have the equipments and other stuff needed You will need a soldering iron and the tip of the iron can not be very big You will need solder wire the thinner the better Solder wick the thinner the better for example 1 5mm 0 060 There are 1 5 meter 5 feet in each package at least two three are needed Solder wick is used for unsoldering the integrated circuit Wrist wrap All of these equipments can be bought from almost any shops who sell electrical components and equipments Radio Shack etc 2 Be sure that the ignition key is OFF and remove the motronic unit located behind the right front loadspeaker 3 Put the motronic unit to the table so that the connector end is towards2. shift lever as seen in the pictures 2 3 and 4 It is the most logical place and it is easily available when adjuctment is needed It is also VERY important to install the pressure gauge in order to follow up the boost With too high boost one can easily blow up the engine It is also needed when the system is adjusted The output to boost gauge can be taken anywhere in the pressurised side of the turbo Example can be seen in picture 6 Installation in the engine department 1 Connect the original air hose H3 from turbo to the lower connector of the wastegate 2 Connect hose H2 from the control valve A2 to the upper connector of the wastegate and secure it with clamp ring 3 Connect hose H1 from the control valve A2 to proximity of the turbo with a spindle as seen in picture 5 Do not drill the hole too close to the turbo mechanism Also these valve hoses are secured by using clamp rings Basicly it can be connected to any place where intake air is pressurised after turbo But the nearer it is to turbo charger the less delay there is in the control That is the only reason why it should be as near the turbo charger as possible 4 Make sure that all pressurised hoses tubes and connections are in good condition without any leakages With low boost standard set up you may have not noticed weak spots but the new set up will not forgive anything Pay special attention to the hose from intake manifold to fuel pressure regulator If th
3. the lid can be taken away Open the screws four of them remove the rubber cap in the middle of the PCB printed circuit board and remove the white teflon shield Lift the PCB from the non connector end a bit and push the connector so you can open the motronic unit like a book Those two PCB s are connected together by using a flat cable do not damage it Now you have a possibility if you want to connect the wrist wrap to other ground point inside the motronic unit There are few cylinder shape electrolytical capasitors in horizontal position in the PCB s The ground can be found from the other end of the capasitor s opposite marking Wrist wrap can be connected there Find out the correct EPROM to be changed If you have four EPROM in your PCB the one to be changed is the S723 If you have two EPROM in your PCB the one to be changed id the S722 If you have one EPROM in your PCB the one to be changed id the S720 When you sure that you have located the correct EPROM make a note which way around it is There is a small dent on the other side of the EPROM in the middle and that shows on which end is the pin number 1 You can also notice a silkscreen printed on the PCB the thick white line under the EPROM tells the polarization of the EPROM When installing a new chip the thick silkscreen and the dent in the EPROM must be on the same side Turn the PCB and find out the pin s belonging to the EEPROM you have to ch

TUOMA PERFECTION OY VER 1 52 BM1A102TK01A BM1A102TK02A and BM1A102TK04A Turbo Upgrade Installation Instructions Material needed Control valve A2 Spindle R1 4 Flexible hose for H1 and H2 connections Wastegate modified by Tuoma Perfection Tuoma Perfection upgradechip or modified Motronic ECU for 3 4 L versions Airflow Meter modified by Tuoma Perfection for 3 2 L versions only New set of spark plugs with better temperature characteristics for high boost conditions turbo pressure gauge hose not part of the upgrade kit First of all the Motronic ECU must be upgraded see appendix 1 It is highly recommended that this is done by Tuoma Perfection or professional person in electronics Reasons are explained in appendix 1 In picture 1 you can find schematic of the Tuoma Perfection upgrade system The flexible hoses H1 and H2 from engine department to cockpit must go through firewall Most of the persons are using original through hole s already existing like the Motronic ECU unit wiring harness through hole Make sure that those holes are sealed afterwards by using silicone or compatible material It is also possible to make a new through hole beside the Motronic ECU wiring harness Special equipment needed is sold in any well equipped car accessory shop also rubber covers for this new hole should be available in the same shop In the cockpit it is recommended that the control valve A2 is located near to gear
5. ange And when you are sure that you have located the correct pins the unsoldering can be started Take the soldering iron clean the solder tip and resolder the EPROM pins on that side of the PCB where is no components by using little amount of thin solder wire This helps when removing of the solder starts Take the solder wick and start to remove solder by using solder wick If the solder does not come out easily in the first time resolder it and try again Remove the solder as well as you can If the solder has been removed properly you should see through the hole When all the solder have been removed from via s turn the PCB open it like a book other way around Now it is time to remove the solder from the other side component side One does not 15 16 Push and pull sideways 17 18 19 20 21 22 always manage to remove all the solder from the bottom so rest of the solder must be removed from the component side Take the solder wick and remove the solder Be carefull and do not harm those plastic capasitors standing in vertical position When all the solder have been removed move those pins carefully sideways by using for example screwdriver DO NOT TRY TO LIFT THE EPROM BY USING FORCE it might damage the PCB Push and pull the EEPROM sideways two times it cause less damage than trying to lift it by using force A
