What did the TPS issue end up being?

I removed the tps entirely and used MAP instead after some wise advice from Nitrodann.

Is it running ok yet?

wait, so if TPS isn't necessary, why does anybody even bother with it?

Why did we ever stop using nice simple carbys :cry:

Heh, try finding a good carby tuner these days. Particularly for something a bit complex.

Yeah sorta, alternator is giving me the shits though lol. Sick of having to jump it every freakin time. I'm going to have another crack tomorrow. I'm still not 100% convinced it's actually the alternator too, it might be the wiring, will check with multimeter though.

As far as tuning is going, I didn't see any red dots come up on the MAP graph in the AE wizard. I get a green bar that travels up and down but it flicks up so quick it's a pain in the ass to determine where it is in the revs and the afr at that time. Might need a second pair of eyes with me.

yeah its the green bar.

RPM is irrelevant, just blip the throttle, accelerate sharply etc, note the afr only WHILE you do it. If its no good and the car isnt responsive glance down and check where the green bar is, now adjust the graph at that part up or down as necessary.
Try to hit all parts of the AE graph by opening the throttle at different speeds (snap to full throttle will be at the far right, gentle squeeze for a nanna overtake will be far left or may not even register).

Done.

I live with one.

And there's another 3-4 at her work that also know how to tune them.

Josh, Would it be practical for someone to film it with your Iphone?

Well it's been a while. Car has gone through some serious changes over the time it's been off the road and now I'm very happy with it. I've even dríven it a few times!

As it is right now, the car is sitting on a nice set of new RS Watanabe Type-R wheels and jubiride flares. I decided in an effort to make the car more simplistic, I traded the black hard top for a red one. It's so much nicer seeing the car all one colour again, I really miss that.

As for driving, that part is still a little rough. It's getting there on the tune but holy hell does it put a smile on my face

. I now have big respect for superchargers. It's not a 'fast' car by any means and sure it probably makes more noise than it does power. But it's sure as hell faster than a stock na6 and it feels like it's got the power the car should have had out the factory.
There are some things I don't like with the supercharger, the increased pedal weight, it's not as revy (supercharger seems to run out of steam about 6k to 6.5k), and a loss of throttle response as well. It does however make up for that with a nice steady low down band of torque. Changing gears earlier is a new experience for me, but it also means I don't have to ping the limiter out of corners to get the same feeling. Infact, I've discovered I can get the same experience I had N/A (revving the hell out of it in second gear out of a corner), now calmly in third gear.

The tune is still a ways off where I'll be happy with it and I've also accidentally broken the top off my waterpump sensor (oops :roll:

), there are also a few minor vac leaks here and there too. BUT! it runs and it runs relatively safe for now. The current plan is to replace the faulty temp sensor, go through my whole intake system and clean it up, look for possible vac leaks and make up a more practical CAI that doesn't rattle against my bonnet.
All that's left after that is dyno tuning!

I think I'm done with exterior mods too now. The car has been off the road so long now that I just miss driving it, I'd rather appreciate it from behind the wheel rather than in my driveway. Interior needs a few bits and pieces still though. I have a broken center console that needs to be replaced and side mounts for my bucket seat so I can actually install it.

Hope this vid works

For those who can't see the vid (prob all of you), just a quick idea of how the car sounds now.

Car looks fantastic. Can't wait to see it in the flesh.

So it's running, yeah?

It sure is and man does it run. It's massively fun but not without it's problems. The car is still out of tune but it's certainly getting there.

At the moment I have a dodgey PCV which I think is causing a current issue with idle I have. The other issue is my wideband deciding to throw error codes. I've unplugged it and tried a free air calibration to no avail and tried calibrating in car with similar results. Tomorrow I'm going to try again and see what happens. If it's still throwing the same error code (faulty sensor code), I'll bite the bullet and buy a new LC2 kit.
The current wideband is an LC-1 I bought second hand on the cheap when I had the supercharger setup. I have no idea on how many km's it's done or it's history prior to me owning it, so maybe it's better in the long run to just replace it anyway.

Boost control has been set up, though the car is still running at standard wastegate pressure which (I'm guessing is about 7-8psi) with boost control turned off until I fix this wideband situation. None of the VE tables have been set up for higher boost and without being able to have an indication of AFR's, seems like a dumbass idea to turn boost control if I'm missing crucial information.
Though it is tempting to see what the car can really do.

It's been fantastic driving it this past week tuning though. The second I sat behind the wheel of a stock na6 after driving my car, I realised I've really made the right decision. I have to say, for a semi tuned turbo car with a dodgey idle, it is so much more gratifying to drive than the supercharger ever was. Quieter, a damn sight faster, and much more drivability. Off boost it just feels like any other mx5.

I'm hoping when the muffler has burned in properly it gets quieter. Because right now it's actually decently loud hahaha. It sounds amazing but draws a LOT of attention
