Multiple Tune Question
Multiple Tune Question I was wondering if there is a way to quickly change the tune at the track without having to use a PC. I get races where people want to race me all-motor instead of nitrous which I don't have a problem doing. Trouble is, this leaves me at a decided disadvantage since my tune is geared for a healty dose of nitrous (ie timing retarded etc etc).
Is there such a device that will allow me to do this? If so, where can I find it?

How much power do you think you're really losing by a conservative tune though, 10hp maybe?

My last motor fell from 394 to 375 rwhp (all motor numbers) when we cut back on the timing to run 150 shot. Definitely enough to make a difference at the track.
Back from the dead. Any other options out there? Auto-cal is still beta testing, I believe. Does something like Auto-cal save only efi-live files? For example, would it store files (tunes) done with other software like HPtuners? My tuner (efi-live) is getting out of the business and my next choice uses HPtuners. I still want to be able to switch between tunes but AFAIK Hptuners doesn't have anything to do this.
SCT makes an X3 device that will do what your asking, it will hold 3 custom tunes.
Or you could go with COS5 from EFILive with a n20 and a normal mode. (switch that alters a few tables)

The dual flash chip may be cheaper and is also a good idea but why do you say with a timing tuner or retard box the dual chips is far less hassle? All you do is basically a flip of a switch with the retard box..

Because with any of those kinds of items you are intercepting signals via splicing into the harness in one form or another and modifying the original signal. That alone adds hassle and reduces the integrity of the loom. It also messes up the engine bay with unnecessary hardware clutter. Far simpler, cheaper and more reliable to keep it in the PCM and only have 1 extra wire coming out of the plug to initiate the n20 changes.
The dual flash setup certainly has much promise. I have one coming to check out.
A 2bar tune for pump gas and the street; flip a switch and move a MAP connector from one sensor to the next (or relay to the switch that moves betweden the two) and get a 3bar setup for high boost and race fuel and real time tuning on both sides ... nice.

It is no more or less complicated with the exception of the additional sensor and relay to switch it over when you command the cal to switch... The 2bar map has 5kPA steps in boost area where as the 3bar has 10kPa steps north of 105kPa. There isn't a huge difference either way, but I tend to the run 2bar whenever it won't be maxed out.

you could just get a lingenfelter two step with the timing retard function built in. i've got one and i havent used the retard function of it yet but you do have the ability to retard up to 10 degrees of timing and it plugs in on top of the factory coils. my roommate got one and used it on his 408 H/C/I 300 shot and it worked flawlessly.
