wakeabby14 Posted February 16, 2017 Share Posted February 16, 2017 Im new to this stage of where my car is now I have a few questions. First of all at the moment i cannot afford a wide band sensor so im a little hesitant to up the boost any more as im currently running 0.8bar on a CT9B. Im a novice so bare with me if i ask some stupid questions. 1) How much boost can the stock fueling cope with? Injectors ect.. 2) Due to me having a JAM ecu in the car do i need a FPR as is it adjusting the fuel already as it will have a more aggressive map so i can up boost to 1bar? Current spec (that is relevant to this topic)...FMICJAM ECUMagnecore HT leadsHKS actuatorTOYO sports manifoldCold air intake Do you guys think i will be ok to up my boost to 1.0bar as i want a little more power or what do you recommend? Possibly the cheapest option as dont have a huge amount of spare funds. Josh Quote Link to post Share on other sites
adzy Posted February 16, 2017 Share Posted February 16, 2017 Everything you have will be fine for 1 bar on a ct9, the only concern would be how lean or rich the jam ecu would run. You could take it to a rolling road and get them to check your afr for peace of mind. Alot less than the price of a wideband Quote Link to post Share on other sites

Alot less than the price of a widebandYeah thats a good idea actually, Im pretty certain there is a garage close to me thats a ford tuning specialist im sure they could easily do it but i think they charge £70 per hour! ill have to have a look around but thanks for that input man Edited February 16, 2017 by wakeabby14 Quote Link to post Share on other sites
daniel_g Posted February 16, 2017 Share Posted February 16, 2017 (edited) The P&P ECUS as a rule run rich. Some people say those ECUs also prefer stock injectors, as stock injectors are good for 1bar TD04 builds you might aswell just keep them.As for a FPR, quite a lot of people keep them stock. Imo theres no point buying one unless you can monitor the results the adjustments make, ie on a dyno or with a wideband.Ad say bang the boost up to a bar and enjoy.

daniel_g Posted February 16, 2017 Share Posted February 16, 2017 What you should probably do is buy an uprated 255 fuel pump, ad advise an aeromotive one.The stock pump will be about 20 years old now, mod ahead before shit breaks is what ive tried to do Quote Link to post Share on other sites

Just a little nervous as dont want to destroy my pride and joy haha!Thanks josh Quote Link to post Share on other sites

I will probably put to 1 bar and do loads of research before even considering melting a piston at 1.2 bar or anything else haha! Josh Quote Link to post Share on other sites
