Title: Re: difficulty with cams comp Post by: tjwasiak on June 17, 2014, 10:48:25 AM Your camshafts must have big overlap. You should advance ignition and raise idle engine speed so the trims would be normal. IMHO such cams are not any good when used with stock engine management based using MAF sensor.
Title: Re: difficulty with cams comp Post by: Jordy971 on June 18, 2014, 09:16:12 AM Advance ignition on all map ?
You think 1° will be good ? Title: Re: difficulty with cams comp Post by: tjwasiak on June 18, 2014, 09:19:46 AM Not at all maps for sure!
You need more advance at idle and low load/low engine speed and less advance at high load/high engine speed. For example I had to bump ignition advance like 6-7* (to 15* BTDC) to make it idle. Title: Re: difficulty with cams comp Post by: Jordy971 on June 18, 2014, 10:04:13 AM Oh, okay ! Thank you !
With good ignition and good tune on TVUB and KFKHFM I think i will have a good idle And for Partiel load I will use KRKTE ! Title: Re: difficulty with cams comp Post by: tjwasiak on June 18, 2014, 10:12:13 AM IMHO you are still wrong.
KRKTE, TVUB and KFKHFM are not the maps which one should tune to alter fuelling. You need to touch them only if injectors or MAF sensor are replaced with different parts. There are proper maps to tune your fuelling... Title: Re: difficulty with cams comp Post by: Jordy971 on June 18, 2014, 11:25:54 AM Yes, I have Injector 1000cc, and Bigger induction (100mm)
Title: Re: difficulty with cams comp Post by: tjwasiak on June 18, 2014, 11:55:44 AM So you will have big issues to dial in everything at once if you do not have data for such injectors and MAF correctly dialed in...
Title: Re: difficulty with cams comp Post by: Jordy971 on June 18, 2014, 12:32:50 PM I have found good data sheet for Injector 1000cc EV14 and I will use software on this forum for scale MAF 100mm
Title: Re: difficulty with cams comp Post by: tjwasiak on June 18, 2014, 12:45:35 PM Unfortunately it is not that easy. That way you will get data which is not perfectly precise but still better then taking random numbers. That is why I am always suggesting to dial only one part at time. Running wilder cams will make dialing them even harder.
Title: Re: difficulty with cams comp Post by: Jordy971 on June 20, 2014, 10:49:51 AM Yes, I will need a lot of time !
Title: Re: difficulty with cams comp Post by: Jordy971 on July 04, 2014, 01:35:44 PM My car is very lean at idle with camshaft competition, you think increase fkkvs at idle will be good ?
