ECU flash for 3.4 conversion near Denver, CO

[Jake Raby]

Most 99s are not tunable, not all have the 1Mb file size, some are 512Kb sized and can't be flashed (5.2.2 DME). The 996 ECU (7.2DME) is a full 1Mb file, so you can't load it onto the 5.2.2 ECU.

You'd have to have a tune configured based from a 512mb OE file. I've had luck starting with a 5.2.2 BMW file, then building my tune tables off that.

Been there, and done that.

I've been looking for a 996 911 ECU online and noticed my boxsters Porsche part number is identical to the 996 ECU's I've found (996.618.601.04). Is there a bosch number or other indicator of whether or not it's a 5.2.2 vs a 7.2?

This is a great topic.

I am also in the same situation, with a 2000 boxster 3.4. Assuming we have the bigger 1MB ecu, after its been tuned to a 3.4 ROW spec, how can it be flashed for more power?

Jake Raby, do you have a tune for Soccerties and I?

Where is tod Holyoke when you need him. He flashed mine years ago when I did my swap. You will still have to tune with a piggyback controller or get it tuned. You afrs will be way off.

He moved out of the U.S., sold all his Boxsters & sold his PST2 to me.

I don't do tunes for engines that we haven't built. I don't believe that these ECUs can be properly tuned without having the car on hand and performing a live dyno run, while monitoring OBDII and stand alone data for enrichment and spark advance. This is what we do on site, when tuning.

I see generic tune files cost people engines on a routine basis. Part of this is due to generic tuners jacking up timing and other parameters only to make power, when they don't have the proper mechanical knowledge and experience with the engine to truly know how these changes can possibly impact the engine in a negative way.

The last tuner that I talked to didn't even know the 4 strokes of a 4 stroke engine without Googling it. How the hell can he tune an engine?

I have tuned 5.2.2 ECUs, the only one that can't be tuned is the 97 Boxster.

You should be able to hook up a PWIS tester (jeez I hope I have the acronym right) and push the 3.4 tune.....it should be selectable on the machine. I would imagine most indies would have one if they are Porsche specialists. ......believe you also need the immobilizer codes for the ECU to allow it.
