    programming

    I found a thread once but the guy got banned and it's been several years since the thread was last posted. But my question is as follows:
    What kind of programmer would I need to buy to allow me to tune the eprom chips we have in our dme's? I'm not doing this to sell them just so I can tune my setup is all. Also what kind of eprom chip would I need? Thanks for any info you have.

    Probably going to a dyno place would be your best bet, but some of r3vs more proficient electrical engineers may have the knowledge too. I know there are a few guys who build and program MS2/3 setups for people here.

      Yeah but I'm only going to run ms on one car eventually. Going to a dyno would be a waste of money for me, I like tinkering with it way to much. Plus I'm going to own more e30's and figuring out how to tune now would be way less $$$ in the future.

        If you want a temporary thing pick up a Dinan or MarkD chip for your ECU for now.

          If there cheaper I would but I plan on building another but staying n/a so I need some sort chip for that, along with bigger injectors, maf, ect. If war was cheaper I'd do that in a heart beat because of there tuning program but it's still a lot of money for that.

            There really isnt much if you plan on building up the stock engine, either war or MS2/3. Personally id wait until your actually building it up, or id do megasquirt now if your DEAD SET on building up the stock engine.

              Whell the turbo build will have ms but that build is being done in sequences. The n/a would be basically a Alpina B2.7i, I'd just buy one those chips but they're rare/hard to come by. Or do you suggest still running ms on that build as well?

                Its not unheard of to pull 10-40hp out of an m20 just running megasquirt with a really good tune. Its really all up to you on how much money you want to spend. I was debating running ms2 on my m20, but im starting to think on a different motor so now its all up in the air.

                  Wow didn't think it would yield that much just running that. But I'd still have to convert my other eta to motronic1.3 to even run it correct?

                    Lots of data there. It requires a bit of initial investment but from there on you can tune any m20, m42, plus who knows how many other cars really cheaply. It seems like a great choice for someone to easily break into tuning.

                      Thanks, been reading through it but I don't know what equipment is needed to be able to do that still.

                        From a hardware standpoint, it's not expensive at all-

                        the chip burners are $50, the chips $4.

                        The much harder part is getting the right data into the right
                        parts of the chip so that the ECU accepts it.
                        From secondhand browsing, you'll spend tons of time getting the data
                        files just right, checksums calculated properly, etc, if you start from scratch.

                        That said, if you can find Dale Beuning's contact info (try at http://www.bmwpugetsound.com/vbb/index.php) he was doing chips a while
                        back, and is a software/electronics hardware sort of guy...

                          Perfect Thank you, time wise isn't an issue for me. Having a 6mo daughter kinda requires me to be in the house and help out while I'm off work. As far as starting from scratch, I was going to load up a stock chip on one of my several backup 027 dme's and see the layout and play with the data a bit.

                            From what I understand, you don't HAVE to buy a chip burner, you can leave the Ostrich 2 hooked up. I think a lot of them are using Tunerpro. You can download a stock tune for your ecu onto the ostrich which plugs into your chip socket in the ecu and then connects to your laptop. Then tune it with tunerpro. Once you're happy you can burn it onto a chip.


                            There's also some tuning info on the volvo forum tubrobricks. They use lh jetronic which came with a MAF sensor, and during the same time we were still getting AFMs, wtf?!

                              Well the ostrich is a good idea but as of right now it's initial cost starts out 3x the amount of what I have available at the moment.
