Quick visit to test my sig, Oh and to say hello to everyone here

Roadsport SV 1.6 Sigma 150

in Viper Blue here

My 150 is doing about 34 mpg, with an element of heavy right foot, which is not too bad, will have to see if it improves after it has gone in.

Although, of course, since posting on here, it hasn't played up at all !!! The power of Blatchat eh ?? 😬

Okay, booked into Cat Mids in a week or so. Further investigation shows that it is lumpy for more than the 40 secs, so maybe not the mapping, current thought is the throttle body set up.

But of course, it won't do it now will it !!!!!!!!!!!!

Thanks everyone for your thoughts

The car did have the latest maps when it was serviced late October prior to me collecting it, but there is apparently a new one out now !! So will talk to Nick / Jody at Midlands (thanks Mav)

h___ , no haven;t got a Master Switch, so always use the ignition key, although I noticed on Scoops thread, Mic said that :-

"When starting DONT touch the throttle as it will alter the ECU settings." which is probably something I do out of bad habits.

Thanks for the comments, I will do some more experimentation as to the temp of the engine when it does its thing !

Eccles, from cold it runs absolutely fine, slightly fast idle but no lumpiness at all, it is only when stopped for 5 mins or so that it thinks about playing up.

My Roadsport with the Sigma 150 runs well 99.5% of the time, but recently I've noticed that if you stop for 5 minutes (to buy a paper or some mik) the engine runs lumpily on the restart (to the extent it will stall if allowed)

Its almost as if a couple of cylinders aren't firing. After 20 seconds or so of increased (lumpy) revs, it sorts itself out,, the cylinders kick in, and runs as sweetly as ever.

So not a major problem, just a niggle.

Any ideas ?? I did think that it may be fuel evaporation due to heat, but when it is running lumpily there is a smell of petrol from the exhaust so perhaps fuel is getting though ??

Over to the power of Blatchat................ Thanks

Final Update 23.06.09

Please see post on 23rd June, after the latest map, Rev H, car is now fine and was had a dyno run at Northampton Motorsport. Figures are more than acceptable, so I'm happy again 😬

I too, have noticed something similar.

Being in the midlands (South Leicestershire / North Warwickshire) there seems to be little on Chitchat about what people are doing blattingwise or meets locally. I know occasionally there is a thread, but you have to go back a long way to find a Warwickshire meet or Leics, Derby etc thread.

Is there any merit in considering another group of threads, i.e.

Chit Chat, Tech talk, Local Area etc and then in the Local Area part, you would have stickies for the AO's (or others) to post threads for their area. That way you would only have 15 or so (how many areas ?) threads, but each one would be a record for each area ????

Pardon me if I'm speaking out of turn being a newbie, but its a pain trying to find details of people who may have posted on an old thread about a meet

Seen on the A426 Southbound at Blaby, South Leicestershire about 1.30pm, and then perhaps again at Caterham Midlands later ??

Looked shiny and new anyway !!!

Seen in Binley Woods, between Rugby & Coventry, going towards Cov. I think it was a 7..........but I wasn't really concentrating (on the 7 !!!)

Should have said, about 1.30pm ish
