does anyone make one for a ls1...or can you do it with bs3

run maybe a low boost pump gas tune then with the change of a button run your racegas high boost tune?

i know mustang cobra guys have it and they can have like 5 differant tunes and change them while driving...

 

I believe you can do that with a Roadrunner, but it's a bit pricey. Look in the PCM Tuning subforum for more info.

 

some1 move this thread..i put it in the wrong forumn

 

Moved from conversions and hybrids

 

i guess what im getting at is how do guys run like 10 pounds for a daily driver then up it to say 20 or whatever is safeest they can go on pumpgas? then do they just pour in racegas and run say 28 pounds? no timing or fuel adjustments? i know the map will adjust for the fuel not sure about timing?

 

You can do it with EFI Live with custome operating systems. You can flip between two tunes with the car running. It works really well for boosted or N2O cars.

 

cant do it on the dbw truck pcs can u??

 

Dead on, EFI Live can do this for any 99-03 LS 512kb PCM, which includes

99-02 F-Bodys
99-02 LS powered trucks
99-03 Vettes

 

Not really 2 tunes, but yeah the capability is there to effectively run 2 VE tables via the VE Multiplier when the switch is grounded. Spark works in a similar manner but the modifier is a +- value to the normal spark with the switch grounded. Both these tables aren't fixed either, rather they offer the modifiers to be applied at different RPM's. The modified VE can also be switched on at a commanded MAP in conjuction with the switch if desired.

This operating system is of course free from EFI LIVE
