Who has had a remap!

[Bealo]

We custom map all the cars we remap, there are different levels for different mechanical differences. A stage 1 file (standard car) is more about how the power is delivered rather than bigs gains, stage 2 (full exhaust with cats) is a bigger jump and we make much larger changes to fueling as the airflow is increased. Stage 3 adds the manifold which on its own adds 8-10bhp so we again make larger changes to fueling and timing. Stage 4 adds cams of which there are three different versions from Schrick which need different options as regards rockers, retainers etc. You cant fit cams unless you map the car to suit or it will run lean.

The maps are quite different to M3's due to airbox. Superchips is our mapping partner but all the maps we do are ours only and custom done on the dyno.

Race car maps are a version of the stage 4 although we move the torque range around depending on what we want, on my race car last year we tried about 6 different maps some with high end power (start of the season) and latterly with more power lover in the rev range (we disigned the manifold to achieve the same thing) and the result was a quicker car and lower lap times.

Thus far we've mapped/upgraded nearly 130 CSL's in the UK, and if you dont like what you get I'll take it off and refund you.

What do you regard as a custom map? When my stage 2 was fitted we run out of time at the end of the day and you put on a map you had. We didn't have time to run my car on the rollers to check everything. But all seems good and i'm happy with the car!

Yeah I remember, we did a couple of adjustments but ideally I'd like a final dyno run on it. Sometimes we do run out of time but thats why we really say we need the car for a full day.

How much of a difference does the dyno make then ... ?

Rich just put mine on over at the Race Wkshop so no Dyno solutions on mine

A custom map is a map which is tweaked either on the road or dyno. If no road or dyno then they were just a generic map to suit your stage of tune. Most maps are done this way.
A custom one is a generic map that is flashed on and then certain areas are changed accordingly. This is the safest way and best way to tune.

A run on the dyno may not yeild any more power that is truly noticeable Daz, but it will show how well/ bad your car runs with the map. It can highlight any fuelling issues which can duly be changed.

IMO a map is only deemed safe when it is checked on the rollers/road, the dyno is a tool, not always for power figures either.

Im not saying lots of testing/research does not go into flashed generic maps, as most of the time it does, however there are some very crude flash maps out there. But every car is different so a custom map is better every time.
