Right! It's not like any 7 is a common spot especially this time or year! there was a few nice cars out mind, us obviously, but I also saw a deep blue Ferrari 812, and a 911 resto mod... do you gents ever go to the pub meets locally? I'm still fairly new to the scene, but would be good to meet other like minded local (ish) owners and petrol heads.

Well it looks good from behind! Is it an exige 430? Wasn't going to get close enough to read the badge in those conditions! cracking colour and a great car...

Could also have been me! @benton were you in a bright orange lotus per chance? I followed one through ranmore and down Crocknorth hill late morning/ 12 ish. I remember you having one, we've exchanged waves before around that area. I lost contact with you at the end of Green Deane turning onto the A246! I had just picked my car up from GP sevens after some mods and TLC... Sounds like two orange 7s out though

I use two of these for our outdoor stored MG BGT and MG Midget can't beat them. Fully encased, with airflow and and they don't touch the body work once they're up... Even routing for battery charger cables... Takes about 10mins to get the car in and out being careful of paint etc... https://www.carcoon.com/product-range/vehicle/outdoor/outdoor-carcoon/

Thanks for sharing. Sure it will help someone! I'm sure you're not the first and won't be the last person to do similar! I've done some daft stuff in my time too!

Worth ruling out a bad earth. My gauges were doing all sorts of mad stuff. Turned out to be a loose main earth next to the fuse box under the dash. For the sake of a 5 minute check...

yup, whoever fits it will need to map it for you. There is a specific 310 map to ensure you get the benefit from the cams etc.

Sadly none of the Ti-VCT sigma's are fitted with a LF as standard. The supersport option on the older fixed cam sigma's doesn't seem to be a thing anymore! But they come alive with one... the 310 just has a set of cams and a map over the 270. they're otherwise the same.

Morning all. I had this exact issue described in the initial post. Adding my solution here too incase it helps someone else in the future. Looks like your issues were solved @frogman - "tag waggling"... For ref: 2016, Sigma Ti-VCT car with stock electrics, including the tag/fob immobilizers and ubiquitous red starter button... My symptoms: ignition on, fuel pump primes, immobilizer LED blinks fast, waggle tag till immobilizer clicks, Red LED goes out - should be good to go - press the red button and silence. No solenoid click, no crank nothing... It went through a few weeks doing this intermittently, some times taking 3/4 or even 5 goes before everything magically comes to life and it fires. Then it just stopped starting at all - fortunately in my garage, rather than mid blat. Checked all the under bonnet connections, clean and tightened etc. Nothing worked. Q much searching on here, and some kindly provided wiring diagrams from ever the helpful membership (you're all legends). Then an evening spent with feet up the roll bar and head under the dash with diagram in hand. Multi Meter generally getting tangled. Realized that all the dash gauges and switches all come back to a single main earth by the fuse box. Located and wiggled the earth. It proved to be "comically loose". Tightened down with a new nylock nut from the "emergency nut box" Start issues "suddenly" disappear, all rocker switches now glow strongly too...and my oil pressure gauge now reads more strongly... something I previously had in the TADTS pile. Hope this helps someone! Best Kris

Yup, thanks. This is the one I have. Just need to know if there is a later one really. The later engine has all the loom extras for the variable cam gubbins for example. I'd expect much is the same but...

Thanks Jonathan. Your mailbox is full, but I have your address from some previous help. So I've pinged you directly. Hope thats OK. Many thanks... Kris

Thanks for that. I hadn't found that link. All the later guides here are also without wiring diagrams by the looks of things. There is a diagram here, and its the same one I have. Perhaps that is the latest!? I'll roll with it! Many thanks

Morning Campers. Can anyone point me towards a wiring diagram, per the subject please? I have one for the earlier fixed cam sigma, but just need to be sure there aren't any funny updates! The later (colour) build guides don't seem to have a wiring diargram... I'm trying to diagnose some "Herbbie/Love Bug" style intermittent starting issues. Thanks in advance...

Yes very hot! My feet were melting!! Nice to meet you...

Friendly waves exchanged! I was the orange 7 with twin black stripes coming down the hill behind that massive truck!

good to know, thank you.

Hi there Paupa. I'd be very in to interested to know how you've found the PP Ultralight fly wheel vs the one you're selling - a caterham one presumably? I'm thinking about going with PP too and I note that is MUCH lighter than the Caterham Light wheel. Best Kris

I'm not a 620 owner, but have the smaller (lighter engined erhum.) ford Sigma. They don't have any choke mapping in the ecu like every other car, so even they can be grumpy on a cold start. Nothing like petrol ped's vid mind. If the 620 is the same it won't help! So on the cold start point at least, perhaps to a point TADTS?

I'm no expert, but have just recently done my homework on the Sigma's having just bought a Ti-VCT which was moonlighting as an older fixed cam sigma. so, from my reading, the stock 135BHP sigma sold from 2015 on has a 7000 rpm rev limit with peak power at 6,800. So not really any different to the 125BHP . But the 125 hits peak power lower down c6,100rpm, then drops away. Top speed (officially) for the 125 is only supposedly 112mph too. So 105mph in 4th isn't too shabby?? So the 135 map won't give you more revs, but it will give you 10bhp more at 6800. But it sounds more like something else (gearing?) as others have suggested. Worth double checking which engine you have though, as UK cars sold from 2006 to 2015 were all "officially" fixed cam sigma's not Ti-VCTs. There was a 115BHP VCT available during that time, but it was sold over seas only, not in the UK. But! I've separately been told that towards the end of the 2014 the fixed cam sigma supply dried up from Ford (they were End of life due to Euro 4) and the last 125 Roadsports were switched to the Ti-VCT lump, before the 135 bhp 270 arrived in 2015. So your car (think you said was 2014?) could have either potentially. A quick glance at the top of the engine will tell you. Fixed cam sigma's don't have the wiring harness for the solenoid which flips the cam profile... If you have the older lump, you can still remap it, but you might need to look into the 140 supersport spec and map, not the VCT 135 (map, light flywheel, revised air intake with side vent in the bonnet - all standard on the later 270, except the flywheel) My 135 Ti-VCT positively headbuts the rev limiter in all gears and only feels slow when I happen to see a 420/CSR/R400/620 etc etc etc disappearing up the straights!

Top effort sir.

Clearly! I'll look out for you then. I'm often out over that way. I'm near woking, and generally get drawn that way. Thinking about popping along to an area meet at some point soon. Perhaps see you there! Kris

Ha, that was me! Nice to meet you. Your lotus looked lovely. Great colour. Sorry I'm slow off the mark on this one...I'm a newbie and only just found this bit of the forums. All the best, Kris

Taking inspiration from this thread, I think I'm going to give one of these kits a go for the bits on display. I'm going to wrap or coat the headers under the bonnet to help with temperature. there is a number of kits with different sizes of mop but seems quite reasonable to me... https://www.metalpolishingsupplies.co.uk/pro-max-steel-stainless-steel-deluxe-metal-polishing-buffing-kit-3-x-1-2/ might have to wait till some naff weather mind. Having too much fun driving...

This looks like it's worth a go. Are they easy to fit @dave conners ? looks like you need to drill a big hole! I was out for a couple of hours this weekend and my feet and midrift melted. I kept checking the heater was off!! also wondering in wrapping the manifold would help. I notice premier power recommend it with a few of their kits as it helps keel underbonnet temps down... a combo may make things more pleasant on hotter days?

Yes have one of those... But it dips to such an extent you can't see! #sevenlife
