I saw one last year at santapod speedway at their japfest event

I have got a cel with a p0403 error code Forscan is saying valve position control circuit. Short circuit to ground or battery. This DTC may be caused by Damage or worn vacuum hose Egr valve assembly So I have replaced the egr with a second hand OEM one with the same error, I have replaced...

the engine orientation has changed, it takes an aweful lot of an effort to get to the tb, and as of right now, I have a what seems to be an issue with the PCV, the tb is facing the firewall, the intake does a 225 degree turn to come back past the egine block to the fmic, also possible intake...

I might be able to help in a week or so, I will possibly be taking the intake off

I'm back again... Still having a few issues with my build, looks like maybe a pcv issue this time, to get to it the intake has to come out once more, it's a real pita to get out as the tb is facing 180 degrees away from where I want (need) it to be. All aftermarket intakes I have seen, due to...

Answered my own question, after reading the wiring diagram and still not any closer, I watched a couple of videos that gave me an indication of what it was, then a post over here about error code p2006 answered the question. It turns out while everywhere I looked named this as TPS (the tps is...

Still having some issues with my heart transplant, tried to keep things stock but I'm getting to the point it's causing me more issues than it's worth. Making things potentially simpler I'm considering swapping out the intake manifold from the mazdaspeed to the mx5 mk3 intake, there are some...

Well... I was sceptical about it being the maf... I thought I hadn't done anything to it, turns out I learnt something new, they are directional... I had turned the pipe around to get a better fit, little did I know this was going to be an issue, just turned back around and it's starting again...

as some of you know I have been working on a swap for my mx5. I still havent got it running where I want it to, I have had a CEL for my egr, my new alternator with less than 200 miles on it had an issue and I was able to make a decent home made smoke tester and have found some intake and...

Answer is "mostly" - it runs, drives, passes UK regulations (MOT) still working through some issues as can be seen in other posts. I dont belive this is the first one in a mk3 but I do belive this is the first right hand drive one - I just tried looking for the forum post but cant find it, the...

I am attempting to try to finalize my project car, fixed a couple of ongoing issues including a boost leak (there may be more?!). However I am running live data to see how things are running with the car and have noticed that it has a high LTFT around the 18% mark when idle/cruising. I have...

I'm using forscan to log, not needed to tune, wiring, engine ECU, abs, IC, all are out of a cx7 and out in here, I'm going through a list of issues to resolve, got a coolant leak and a boost leak, this abs problem and a few other things I'm not exactly sure what's the issue. I've done about 200...

I wish I could turn it off, on the cx7 it has TSC off, unlike the others that have dsc off... I could swap the abs (and if needed IC and ECU) for a ms6. I would however like to get to the bottom of the issue as it will also be my daily and here in the UK, gets icy in the winter. Just done some...

Hi all, this is going to be a long shot here but here goes. I have a heavily modified mx5 with a cx7 engine and abs unit. Amongst other issues I have a problem where the stability control kicks in when I'm turning a corner when doing over 20 mph, with one side of the brakes clicking in. I...

not over here, full build thread over at mx5oc forum https://forum.mx5oc.co.uk/t/my-current-project-nc-mps-conversion-now-with-pictures-video/137980 its a long read, be warned On a side note, I have been giving this some thought. breaking this down as logicaly as I can. 1. When the coolant...

I was finally able to work on the car today, I got the temp sensor fixed and now it starts first time. I havent ran the engine too long but enough so the temp gauge is now at the half way mark. My concern still is that the turbo is still not getting any coolant unless I put pressure through the...

As some of you know from other posts here that I have fitted one of these engines to an mx5 I got an issue with the engine temp sensor, so I haven't fully ran it for a long period of time. The issue I am having is that there does't seem to have any coolant running through the turbo, I have it...

the thing that gave it away was along with the code, there was no sensor information while running diagnostics with forscan. It could be a normal sound as I am not used to this engine and I cant hear it in the cabin (or probably even with the hud down but havent tried that yet) but there is a...

Great news, we are up and running thanks to your advise. Done some more readings and noticed on one occasion there was a error code relating to the throttle body, this was a second hand replacement of ebay as I damaged the housing for the connector on my original, the connector is in a very...

Update: Thanks to you guys and advise over the 3/6 subforum the engine starts and runs! Few things I need to tighten up and adjust but its a good day when an engine thats swapped cars and been sat for over 12 months starts! Turns out there was 3 things that was causing the issues for it not to...
