AdamB Posted October 14, 2013 Share Posted October 14, 2013 (edited) Rolling road, that's what their made for their a tuning tool. Edited October 14, 2013 by AdamB Quote Link to post Share on other sites
DudFunk Posted October 14, 2013 Share Posted October 14, 2013 Dyno everytime IMO less safety issues and from what Ive seen with dynos you have far more control over the tune Best of luck with it sounds like its gonna fly! Quote Link to post Share on other sites
RobSR Posted October 14, 2013 Share Posted October 14, 2013 Rolling Road, whoever says the road is a pleb. Quote Link to post Share on other sites
akaye4000 Posted October 14, 2013 Author Share Posted October 14, 2013 Cool ill get it set up on the dyno and check it on the road as thought you always get different loads and boost on the road Quote Link to post Share on other sites
AdamB Posted October 14, 2013 Share Posted October 14, 2013 It should be checked on the road after being mapped on a dyno, its just a dyno is a much more controlled state and you can get better accuracy on the load sites. Quote Link to post Share on other sites
RobSR Posted October 14, 2013 Share Posted October 14, 2013 Once its been mapped on an RR, it always will be checked by the mapper on the road. A full map on the road is just gash tho. Quote Link to post Share on other sites
triple j Posted October 14, 2013 Share Posted October 14, 2013 U need the dyno to see when its makes peek power, only way on the road u can find this out is with a g sensor, dyno is better but the road map works for me. Quote Link to post Share on other sites
RobSR Posted October 14, 2013 Share Posted October 14, 2013 You can't map to MBT on the road , which is why it's not brilliant. Quote Link to post Share on other sites
mi16chris Posted December 16, 2013 Share Posted December 16, 2013 (edited) You can't map to MBT on the road , which is why it's not brilliant.u can't map much on boost load sites on a high boost starlet to Mbt on road fuel any ways u will be knock limited , Edited December 16, 2013 by mi16chris Quote Link to post Share on other sites
Stu Posted December 17, 2013 Share Posted December 17, 2013 Road tune does have its place thou and in my experience they both have merits - especially if your starting fresh with a new ecu and/or money conscious. I tend to get a car going and then road tune first to get the majority of the map close and spend a good amount of time on the light load/cruise. Heavy load can be setup on the motorway without getting in too much trouble but it is hard on the car loading up on the brakes. You can save considerable dyno time that way. Then I tend to head to the dyno for overall checking and specific load areas ie full load at max rpm. It can all depend on the setup too. I've got a big database of tunes saved now so can quite quickly adjust to suit a specific setup. Have had a few where the majority has been road tuned and have only needed a short period on the dyno to finish off as they've been pretty close. As stated above its good to re check on the road after as its real world conditions rather than stationary on a dyno. Quote Link to post Share on other sites
Stu Posted December 17, 2013 Share Posted December 17, 2013 Should really expand on my "It can all depend on the setup too" statement - with more serious setups it can be plain dangerous on the street and everyone should use caution and limitations based on the setup of the car. Had a customer only last week with a big GTX series turbo on a 5e that was very laggy (4500rpm build and 5000prm on boost) and it wasn't practical to tune much of the load above base wastegate pressure (6psi) on the street. The brakes weren't up to the task of holding 2nd/3rd gear to the rev limit at much more than that - where as the dyno is definitely the place for that with the controlled braking. I know a few top level guys over here that say the best place to make a tune perfect is on the track/strip as its real world situations, especially with the single digit passes etc. Quote Link to post Share on other sites
RM15_Glanza Posted January 5, 2014 Share Posted January 5, 2014 Both i know lots of tuners that go out on road for low down on the map and then fine tune the top end and generally all over on the dyno. Each tuner to their own opinion tho whatever they are best with Quote Link to post Share on other sites
TurboTobz Posted January 5, 2014 Share Posted January 5, 2014 Ideally both but dyno if you have the choice of only one or another Quote Link to post Share on other sites
