MINT MK1 MX 5 Turbo FINALLY Finished
Discussion
Car is going down to Dave at Valley5 on the 19th October for a full live map of the ME221 as I am still on a base map which whilst this drives well, the cold start and idle could be better.
I am assured that the car will drive beautifully after this and the 4 hour drive back should give me time to appreciate the differences!
Looking like she will be put back in to hibernation for the winter and hopefully finally enjoyed in Spring 2019!
Will post an update when she is done.

I am driving down early Friday for the live mapping and I am staying over on the Friday night so that the cold start can be perfected on the Saturday morning
Valley5 are the "go to" mappers for ME221 so have a huge amount of experience so they know how to map the cold start without having to actually have the car "cold".

450 mile round trip on Friday including mapping and all I can say is WOW!
She made 238bhp at only 9.5psi before we maxxed the RX8 yellow injectors at 86% duty cycle.
Dave (ME221 genius) said that the pipework (all mandrel bent) and large intercooler setup must be flowing beautifully as she made strong power at such modest boost.
The car is now NIGHT & DAY different to how she ran on the G19 supplied base map and she now starts on the first turn of the key and idles rock solid. Boost starts to build from around 2,200 rpm and hits peak at 2,800 before holding strong until the 7,500 rev limiter (Dave knocked this back from 7,800 as there was no gain over 7,500 so gentler on the engine).
This was all on actuator controled boost as I don't have an Electronic Boost Controller (EBC) fitted (now on order!) so there is more to come.
Will be returning to Valley5 in a few weeks with larger Blue injectors (540's), EBC, variable Throttle Position Sensor which he says should produce a safe 260 to 270bhp whilst limiting torque at the bottom end to safeguard the standard rods.
Anyone that is running an ME221 on a base map is seriously missing a trick as although the car will pull great on boost, they run like a pig on idle and part throttle (mine did). You won't realise how bad they are until you get it properly mapped!
Dave first sorted the idle out (took him about 10 mins to nail it!), then she was mapped on zero boost before we steadily increased throttle (and therefore boost) on a few 4th gear runs. Once all this was perfected and the smoothed out we then did a few full bore passes up to the rev limiter in all 5 gears (on a private road of course) and he massaged the fueling to get her absolutely spot on.
The only down side was that I managed to set the standard brake pads on fire when braking from repeated rev limiter passes in 5th gear
Having wanted to keep the car looking standard it is now not going to be possible as the brakes, wheels and suspension now need to be upgraded to cope with what is under the bonnet!
We will see what she goes like with 260-270bhp in a few weeks before I look at a forged VVTi lump with a GT2860 bolted to it with a late 6 speed gearbox for the whole 400+bhp experience!
She will also be visiting Jack Smith Trimmers on the next trip down to Valley5 for a new Tan Mohair hood and maybe a set of re-trimmed Lotus Elise seats to hold you in better!
I am very impressed with the bang for the buck that these little things offer!
Watch this space!

I will be keeping the car now as the project is entering a "NEW" phase!
Bigger injectors (Blues) have now been sourced along with the EBC and Variable TPMS.
I have also bought a custom Wilwood 4 pot brake kit (front and rear) with floating discs that should just squeeze under the standard 14 inch wheels so she will now stop as well as she goes.
Also have TR Lane roll bar with additional door bars on order. With these fitted plus an underfloor ladder brace (Ultra Racing) she should be tight as a drum.
Still pondering Ohlins, BC Racing (remote canister) or Meister R suspension but will be fitting one of them.
The smiles per £ ratio just can't be matched so the car will now be a keeper!
