MAC#1 MX5 Turbo Dyno Run
ash_hammond - 21/5/16 at 06:57 PM

Well the build is coming to an end we are nearly ready for the road.

Yesterday was a very long day which started at 5 am to take the car from Yorkshire down to Emerald in Norfolk for a full mapping session and set up.

To say the car had not only done about 2 miles around the local industrial estate I was very nervous about it having a pasting on the rollers.

John who was mapping the car took his time to ensure things sounded right and got the be basics dialed in. We did a few gentle power runs as things started to come together. Once the car has got warm a small oil leak was coming from a cracked cam cover, this was fixed with a wipe every so often. Also the new clutch was starting the slip. Again a simple adjustment 99.9% fixed the issue. We only got a tiny little bit of slip under max load on one of the final runs.

The car now has 3 maps programmed.

MOT
Low Boost "Eco" Mode of 187 BHP on 9 PSI of boost.
High Boost "Track" Mode of 207 BHP on 11 PSI of boost.

To say I am really pleased is an understatement. I've had a few quick skoot around our estate on Eco mode and it is slightly different to the old pinto!

Here is a quick video the final ish power run making.

Great flutter from the waste gate! Sounds good - i bet you can't wait for full boost mode!

John mapped my car, spent a lot of time getting it right.

Very satisfying day out.

Nice work

Sounds great.

I bet it will be on map 3 most of the time!

100% agree, he is a top bloke. In fact the pre-sales, post-sales of Emerald have been great.

I'm not so sure... the 200 yard dash this morning on the back road of the estate was used up very quickly.

Are the maps switchable in car,or need to be swapped on laptop?

Three position switch plugs into the the comms ports on the ECU, can live switch the maps.

Good numbers and well done on getting it through mapping without issues given the lack of shakedown, must have put a lot of effort in to get it right first time.

Presume the 3 maps are essentially just boost limits, not sure what else you'd change between maps but I can see the desire to limit the MOT guy to actuator boost.

I hate to say this, but, there is an Emerald specialist in Chesterfield, who knows what he is doing.
