hi how and what should i set the co level on a msd chip with 83lb injectors and closed loop do i disconect the lambda and set the co up with the screw as normal on the ecu ifso what should the reading be anything below 3.5% as mot or lower,cheers

 

With closed loop should be around 0.75 m8 once warmed up.Best use MSD 's excellent aftersales service and ask stu,kenny or james m8.

 

Really 0.75% on closed loop, I'm 0.97% WITHOUT closed loop.

thanks chaps i didnt think it was going to be as low as that is that at idle or part throtle say 2500-3000 rpm also do you know what your hydrocarbons are?

 

Question chaps... 1987 3Door ie no CAT Exhaust or Lambar sensor ever fitted, do i take it im allowed up to 3.5 Co. Think this correct...but like to ask any way to be sure. OAP Pete

 

yes mate i think it runs up to 1991(pretty sure) so nice and easy to get a cossie through the test

 

Mine is 0.97% CO, HC is 137ppm, with 200,000 miles on the engine, original bores/pistons/rings, done head though, HC shows mine has not been made lean for the test, as this would go up if that was the case, I'm on greys with t3/34 and ported head etc.

Well done you eh.

 

hi tabetha are you running a saph with cats for those hydro carbonlevel thats pretty low ifso how many cats does the saph run cheers mate ive been strugling to get my kit car through the iva test i didnt think id squeeze it through the hydrocarbons oh and is that at part throttle?

 

Thanks Guys .. just wanted to check... been some time since ive had older Car [ now 3Door ] remember when some years ago it was 3.5 limit when i had 4x4xSaph... but wondered if Govenment messing with it since ? ...get us off road !. Thanks again Pete.

 

I just don't waste my money on systems that are antiquated and bloody expensive when all the toys are added and still don't seem as good as more modern systems, plus mine is mapped properly.
Thanks for your interest though!!

 

NO, not a cat on the car anywhere, the emissions readings of which I'm VERY happy to display were done at my local mot place, and that has no connection to the person who mapped my car, they don't even know each other in fact, and there was NO cheating going on, although the first time I was sweating and was there with my laptop to adjust if needed ha ha!!
The mapper, dave walker wasn't doing anything special, this is on the 300bhp map, I was running around 17.5/18psi due to the near 200,000 MILES the engine had on it, I was also using Comma 20W50 MINERAL oil, as the emissions would have been higher with synthetic leaking past the tired oil rings, hence the rebuild.
I wouldn't waste my money on chips/std ecu's again if I bought another cossie, best money I ever spent on after market ecu, CL makes me laugh, I get that at the flick of a switch if I want, as well as adaptive mapping, it runs better WITHOUT CL, and is better on the fuel as well.
Opposite lock one pf has been in the car and knows how it runs 100% perfect not a glitch anywhere, and idles from cold with no working iscv, as he saw when he was in it.

Tabs,I've bought coilpacks,closed loop fuelling,ALS and L/C and everyone of those things has made my saph better to drive and I'm very happy with them too. Thanks for you interest too.

 

Tabetha, if your fuelling is 100% correct everywhere, and doesnt need closed loop, How many Break points do you have in your fuel table?
