Came across this thread debating the merits of EKU-tek re-mapping in real time on the road versus on the dyno. Some interesting points I hadn't thought of before (once you wade through the usual superfluous comments).

Since Al is now an authorized EKU-tek dealer (and I would like to use Al's services to flash my car; when I get it) I thought he might like to relay his feelings about the relative merits of these two approaches.

Is it better to spend most time doing the re-map on the road and then use the dyno as a final check.....or doesn't it really matter?

 

bump...........for Al.

 

Personally, I feel that only road tuning is appropriate for adjusting a calibration map to match the particular car for safe operation.

Tunes made on a dyno have little application or usefulness in real world conditions.

Dynos are valuable testing tools to determine the functioning of the power train and relative whp - however they are obviously replications of real world driving coinditions.

In my own town, I use the local dyno jet dyno for several reasons:

1 - The traffic density here is almost one of the highest in the USA whcih makes road tuning difficult and dangerous during day time hours.

2 - The volume and frequency over time of tuning I do locally would surely arouse the attention of law enforcement.

3 - I have vast experience spanning over a thousand hours on this particular dyno and I have worked out a method to more closely replicate real world conditions through carefull fan selection and placement, carefull and consistant coolant temprature monitoring and consistant run replication starting and stopping points. All of these methods, worked out over months and months of time have allowed me to very closely replicate real world conditions on our dyno jet dyno. However, I find that the same results can not be obtained on stange or unfamiliar dynos. This is why I mostly do road tuning on tuning trips.

In conclusion, if this is of any help, I get as much free dyno time as I want for my own car - any time I want it. I never tune the car for road use or track use on the dyno. All real tuning is done on the road or track with a real live live load.

Any tunes I do with my race car on the dyno - for example to make a huge dyno number - are useless and need to be discarded when I get to the track as the load is greatly different on the dyno to the track.

Any good tuner can get a acceptable result using either method.

Road tuning is more accurate but requires frequent delays if weather and traffic do not cooperate.

 

Thanks Al; really appreciate your input. How's the ECU-tek working out?

 

So, how does this effect us that are being custom tuned on the dyno for the Atl dyno day? Are our maps going to be unsafe for road use?
