The traction control probably makes a difference, VSD probably will too.

Sorry guys. I've been meaning to talk to Technosquare and have just been real busy. I'll be contacting them for sure this week so I'll see what kind of updates I can get and try to answer some of your questions. On a good note though I spend two days running the Z at Streets of Willow and its performing very well on the track with the new programming. Everything from the throttle response to the extra 500 rpm give the car a nice advantage.

They said in either this thread or the other one in the Tuning subforum that your mods will affect the reflash. Apparently you tell them your mods and hopefully give them a dyno sheet or file with a/f ratios and they tailor the reflash to your mods. Profink, feel free to correct me if Im wrong.

Mods will have a bearing on the reflash. As far as I know right now there are going to be two different flashes. One will be for cars that are still stock with no mods done to them. This will, as dyno numbers have already shown, make some nice improvements in power along with throttle response. The other will be for cars with the normal mods, intakes, HFCs, exhaust. This reflash should work well for most setups as the differences between different cats, intakes, and exhaust aren't going to be so great that a specific program is needed. As far as requiring a baseline dyno with a/f numbers goes, it won't be necessary. My guess is that the A/F isn't going very too much from car to car.

You might want to check out some of the other threads on the HR and intake/exhaust sections. Flowbench tests were performed on OEM cats from an HR, OEM cats, from a DE and HFCs. The difference in flow between the OEM DE cats and HFC is much higher then the OEM HR. Nissan did a very good job designing the cats on the HR. There is also some talk about the amount of airflow required by the HR per intake which may be why we are seeing no gains with the current intakes available to us. I'm going to see if we can do a flowbench test on the HR intake to see how much flow is actually available compared to what is theoretically required by the HR.

I will finally get around to calling Technosquare tomorrow and will update you with whatever I find out.

Some people have been asking about pricing. Unfortunately I can't disclose that as the pricing is not yet set in stone, but it will be less expensive then it has been in the past.

do you have an idea of the gains a car with basic mods i.e. exhaust, test pipes, and or hfcs, and intakes can expect. Also will you have the ability to turn off cel for test pipes?

I'll post some numbers after I talk to Technosquare tomorrow. I'm not sure about the cel, but will find out for you.
