| Yeah, that's a common misinterpretation of a dynochart, so dont fret it. As for your Q on the ECU programming, it is a sensitive topic and I dont want to stir up any drama, so I'll give you a typical response that one would receive if they asked me via email. There are several differences in the apparent philosophy regarding the tuning of an ECU between myself and Mr. Wolf. The largest difference is the lack of a safety configuration in the JWT product, which is used by the ECU when a problem is detected. This safety configuration has been circumvented in their programming while I take full advantage of this feature. In the event that a problem is detected by the ECU, it will revert to the safety maps of which I have properly tailored in an effort to preserve the engine as well as indicate to the driver that something isn't right. If you dont have a boost controller, the JWT product will still indicate when any one of the vital sensors has an issue by means of "safety boost", however, if you have a boost controller, this will not occur and the driver will be oblivious to the problem. My safety mappings will deliver an excess of fuel as well as pull the ignition timing back be several degrees. The effect is that the car will dramatically drop in power. The additional fuel combats the rise in EGT that is associated with retarding the timing while in this mode. This covers the "safety" difference between the two. In the primary "normal" mapping of the ECU, which is used when no problems are detected, my air/fuel mixture target is 11.5:1, which is not as rich as the JWT product. I do this for a few reasons. 1) There is no significant improvement in knock (detonation) prevention by running it any richer than 11.5:1 as knock is primarily dependent on the ignition timing advance. 2) Richer mixtures make less power, and this is the primary reason my programing makes a little more power than the JWT product. 3) Richer mixtures tax the injectors more heavily which leads to a shorter lifespan of the injectors 4) Over-rich mixtures will produce more cylinder wash-down as well as oil contamination 5) Richer mixtures will carbon-foul the rear bumper area of the vehicle. Any Z32 running one of my pumpfuel programs should run an 11.5:1 air/fuel ratio as long as there is nothing wrong with the vehicle. There are dozens of components within the vehicle that can affect the fuel delivery and it is vital that they all be working properly. The ignition timing maps are actually quite similar and may only vary by a degree or two in certain areas of the program. This is mostly due to the fact that, as stated before, knock (detonation) is primarily dependent on the ignition timing advance and fuel octane used. There isn't really any room for variation between one tuner and the next because we are all working with the same engine and the same fuel type. On this note of the timing maps and fuel types, a year ago I put out a new class of programs called my "C" class programming. These programs were designed to cater to those that may have heard something either here or there about my programs being "too aggressive" and wanted something more conservative. This is more/less just a marketing strategy as there is nothing different from the "C" class program than there was originally from my 91-octane programs. I just gave them a "classification" to make it better known that I do have more conservative programs available upon request. I am unaware of anything avaiable from JWT that takes the differences in pumpfuel octane into account. They do have something along the lines of a racefuel / pumpfuel setup though, of which I also offer for an additional $100. This is a dual program setup that the driver can toggle between at the flip of a switch. These are the primary differences between the programming philosophies, however, I can't speak for Mr. Wolf himself - this is just how it appears to me with what all I have seen. Merry Christmas bro. I'm off to bed.
