Bob,
I e-mailed Jarmo Havulinna at Tuoma on May 14th to try to order a couple of waste gates. He responded a week later that he could take the order since I initiated it before the 15th. I asked about credit card processing and what address to send my wastegates to and he never responded back. I'm now very hesitant to send my parts which I can't live without to someone who takes weeks (or never) to respond. Maybe something like the chip is easier to handle since it doesn't require sending old parts in. Even with the stock wastegate, add a rising rate fuel regulator and a boost and air/fuel guage and the car is "way" more fun to drive with the Tuoma chip. If anybody has any luck getting a chip from Tuoma, please e-mail me at Stevecots@aol.com. I have a couple of friends who whould like one. steve

I used the schematics that Bob sent and I found out every thing is OK on the pin side. I also used an oscilloscope to watch the signals on the pins. I pulled out the EPROM from the ECU and took it to an ECU repair shop. The technician checked the chip and there was no program in it.
Now because they do not have my ECU's (0 261 200 013-Bosch)program I need the program or a new chip. There is a number (2 537 355 977) on the label sticked to the erasing window of EPROM. Probobly this is the software no.
Does anybody knows a place that I can buy the program or chip. I prefer the program because I can download it from internet after paying which is quicker way.
I thank you for your help.


My suggestion would be to email Timo with Tuoma Perfection for the BIN file on their upgrade chip. Their chip removes the boost limiter inherent in the stock chip.
