Hello all, My eunos is booked in for its first MOT under my ownership this weekend. The purpose of the car is purely to do a couple of track days here and there so I have striped as much as I dare out of her whilst hopefully keeping her road legal, got rid of the standard seat belts etc and replaced with 4 point harnesses.
I bought the car supercharged but I have had to do a bit of work to her, replaced the head, got rid of the bipes and AFPR and replaced with a old diypnp ms1. The map is unknown on it (I havent driven the car under boost but she idles perfect on the map at a steady 14.7 on the wideband when warm), I have changed the injector sizes and set the base timing etc in tuner studio and burnt to the ms1. I have also replaced all the pads, disks and fluids etc.
So basically my worry is as I havent driven the car on the road I havent bed in the pads, as I cant legally drive the car on the road I havent been able to use the auto tune feature in tuner studio to generate a map suitable for my car.
Is it likely this will cause the car to fail its mot on brake efficiency or as its not mapped properly even though it a eunos fail on high emissions?
Can you think of any area's that are common fails on an mx5 that I should double check before Saturday?
All help much appreciated.
Lee

I doubt they will fail it mate unless they are complete knobs, they will see you've made the effort to put new disks and pads all round and they won't do any emissions testing so you'll be fine  ?? |

It still has to pass emissions doesn't it? Just not so stringently? (I am more asking as mine is in a very similar position to this and I too will need to get an MOT soon!)

Thats a good point, you can see that they are new.
When I turned the car round yesterday and drove along the drive, the car bogged down and had a fit when it went into boost, obviously as its not yet mapped for it. Could this cause any issues? do they just test the car on a fast idle, sorry not sure what they do at MOT. Also will that car be okay with just harnesses and no standard seat belts?
I did print out a MOT checklist but it didn't mention anything on harnesses.

I did read somewhere that the allowable emissions on a eunos is twice that of a UK registered MX5. That was info from facebook mind!! |

Are you taking it to a sympathetic MOT station? perhaps one that does a few modified cars etc? If you are brake testing it, do you have an LSD? If you do, tell them and you will have to do a tap test rather than cocking it up on the rollers.
You could run auto tune on the way to the MOT station.

He has been quite sympathetic in the past but if its an outright fail he would fail it. The MOT station is literally a mile if that, dont think that would produce anything useful in tunerstudio?

The majority of the fuel in the tank was from last September but saying that it was drained from my other mx5 that broke down, about quarter of a tank in there was from about two years ago. It does have a new fuel filter on.

I had the same thing with some fuel from october. My car was running rough (sounded like a scoob) and couldn't really make boost (hesitation). Topped it up with fresh SUL. Runs fine now.

What year is the mx5 if before august 95 is comes under a non cat test so higher emissions limit after that it goes to a cat test. The brakes have to be seriously bad to fail a mot test so shouldnt have nay problem with them.

As long as it idles and fuels correctly you should pass fine. Just sort that fuel in your tank out. Mix it down with a greater amount of fresh SUL - the older it is the more good fuel you want to mix it with. Putting a new fuel filter on won't magically improve the state of the fuel, all it does is stop prarrie canoee in the fuel and parts that fell off the insides of the fueltank/fuel lines getting to your injectors.

Cheers for the replies, the car is a 91 and been an import shouldn't qualify for the full emissions test so I have read.
Car idles perfect once warmed up but does suffer with cold start issues on the ms1 but will have a good play with that once I get her road legal.
Going to go over all the nuts and bolts tomorrow evening, noticed tonight I had missed 2 bolts when replacing the dash which was causing it to twist when turning the steering wheel, the joys of having a small garage and only having access to one side of the car at a time.

Not the best start to the morning, car just stopped on the way to the mot station. Dials went blank on the aem wideband and boost gauge. Turned off ignition but the fuel pump was still working away. Lifted the bonnett and one of the injectors was clicking away.
I shook the wires around the cas area, tried the car and she started up. Took the car back home.
When i got home, looked around the cas area and i noticed the earth point on the back of the plenium intake was loose. I tightened it up and drove to the mot center without problem.
Was it just coincidental that the earth was loose and could this cause the car to stop and not fire back up.
Cars now getting mot and just waiting for the call. Fail or no fail, so excited!
