Jul 24, 2008 - i have installed the stag 1 with mscai, i have a hybrid turbo xs bov and my car make back fire each time i shift and sometimes during accélération. do you think it is cause by the bov

rmcat Says:

Jul 24, 2008 - yah,it must be your bov that's causing the backfire,but every time you shift?that's kinda weird though,how many washers you put in the bov?you might wanna check if there's anything else that's making your car too rich,how's your AFR monitored by ap?

H32588772 Says:

Jul 24, 2008 - i put 4 washers, i don,t know my afr, i will check it this afternoon. my car do back fire only in hard accélération, i forgot to write it

H32588772 Says:

Jul 25, 2008 - i check my afr on the ap and in normal run it is between 14.0 and 14.8 and on hard accélération it become more rich but when i shift or when i stop the accélérarion my afr is 29

rmcat Says:

Jul 25, 2008 - backfiring when wot is normal,and I put 4 washers as well,but mine doesn't do it all the time under hard acceleration,just occasionally.Your afr looks okay to me,which map version you're using now?have you noticed how much it becomes at the richest?

H32588772 Says:

Jul 25, 2008 - hi, at the richest, in full accélération, the afr is between 11 and 12. i use the map version stage 1 mscai v101. my cold air is a aem. i had try to replace the factory bov and my car do back fire occasionally, like you. i will try this afternoon to put 5 or 6 washers in my txs bov. i keep you inform

rmcat Says:

Jul 25, 2008 - I know ppl with stock bpv or reci forge bpv experience backfire as well,our car just simply run pig rich lol,5 or 6 washers might be too much and cause compressor surge,4 is what turboxs recommended.btw,v102 just came out you know that right?

Aug 16, 2008 - salut, j'ai pratiquement le même setting que toi a l'exception du filtreur a l'air, j'ai un aem. j'ai installer mon downpipe turbo xs cette semaine et j'ai été très décu. on dirais que mon char tire moins. j'ai installer le stage 2 vers 1.02 sur le cobb. mon afr descent entre 10.5 à 11 en haut de 5000 tours et mon boost ne corespond pas a ce que cobb dise sur leurs cite. je peak a 18.5 mais ensuite je descend entre 12 et 14 aujourd'hui mon check engine s'est allumé qu'es t'en pense

rmcat Says:

Aug 17, 2008 - c'est depuis quand ton chat tire moins?apres t'as installer le downpipe ou apres le Accessport? et c'est quel code(CEL)tu vois sur le AP? ton afr semble correct mais le boost de 12-14 est un peu trop bas,c'est quand il descend a 12-14?5000rpms? je te suggeres de changer ton filteur a l'air si tu veux utiliser le AP car les autres marques sauf Cobb SF/Mazdaspeed/CPE CAI sont pas recommander par Cobb et ils PEUT avoir le problem

H32588772 Says:

Aug 17, 2008 - mon char semble moins tirer depuis que j'ai mi le downpipe jeudi, impossible a mon avis. je roule avec le cobb depuis quelques semaines et avant je roulais avec le stage 1 mscai et mon boost étais correct et mon afr aussi.mon code check engine est celui d'un oxygêne sensor dans le downpipe. je vais ckecker sa aujourd'hui a quel rpm mon boost descend. je vais faire un ptit tour a pont rouge

rmcat Says:

Aug 17, 2008 - je pense que c'est normal qu'il tire moins dans les premiers 50kms-100kms parce que chaque fois apres qu'on install quelques choses il prends un peu de temps pour le ECU pour adjuster,va checker ton LTFT as-tu installer le downpipe et le midpipe ou seulement le downpipe?c'est quel o2 sensor qu'il y a le problem?
