Wow! Advice from THE guru!

Thank's for helping.

Also, as far as I know the stock fuel pressure is 36psi w/o vaccum which should also be a good thing to know.

I've now got the maps from a UK model ECU. They are similar to the USA version, but richer mixture at higher load and rpm, more knock correction and slight timing differences.

Details and pretty graphs on attached spreadsheet. To make comparisons easier, there is now a front page with all the graphs arranged with RPM on the X axis and Load on the Y.



One interesting thing for me is that here in the UK, we have both JDM and UK model SVXes driving around using very different maps. There must surely be some performance difference between them.

I thought you were running one of LAN's upgrades in your car? If so, please don't post them here without his permission.

Or are you saying that you've made your own custom map and you're willing to share it?

No, I am going to dump the factory ROM for you from the upgraded USDM ECU's. I will not share the ecutune software as it is uner Mike's copywrite and I know better If I do tune the car to run better, I will share my finding with LAN from ECUtune so he may take my changes into consideration for his customers if he thinks they are proper. I am not entering the market for rewriting ECU roms, I am working for myself and the end result may be that stage 3 owners could be running better

Which is as it should be. LAN has done a tremendous amount of work (and invested his own $) to get us to this point and we are legally bound (copyright) to respect that.

Cool. Thanks Tom.
I don't suppose you have a Linux computer? It would be great to dump the whole ROM to a file. But unfortunately we don't have a rom dump program for Windows at the moment
