Ok, so back to the INFORMATIVE part of this thread, t
So here goes my first Nistune installation:
Stock ecu

Removing the conformal coating in preparation for de-soldering (note: the conformal coating will get on you fingers) with lacquer thinner.

After cleaning with lacquer thinner to remove conformal coating, I used alcohol to remove residue.

I applied a strip of flux to make it easier to de-solder the holes on the ecu board. The guys at Nistune encourage people to be very careful here during the de-solder process as the traces on the ecu are very fragile.

Using the HAKKO de-soldering tool, I think it would be difficult to use a manual solder sucker that you might find at Radio Shack, or at least I have not had good luck with those devices in the past.

Here I'm inserting the ribbon cable into the board, this requires a little patience as the cable required a bit of wiggling to get all of the little wire to go through the board at the same time.

Nistune recommends tack soldering the cable on this side first to hold it in place before flipping the ecu over and soldering all of the connections.

Soldering all of the connections, for those that don't do a lot of soldering, it is very important to keep your soldering tip clean with a wet sponge during the soldering process.

I know this picture does not really show it, but I'm looking for nice even solder joints that have a nice shinny appearance. If the solder joint looks dull or matte , you may want to flux and re-flow that solder connection.

The last soldering step is to remove the resistor at position R021 to position R020, this tells the ecu to access the Nistune board instead of the normal ROM.

Fitting the type 4 Nistune board, there was conformal coating in two of the screw holes, so I used a dab of lacquer thinner to soften the coating, and the screws went right in.

Done ! Hope to test it on Steve's car tomorrow.
