So back with a pd i'm looking into a bit more umph.. and better mpg which is quite bad really struggle to make 40+ Last time i had a bora highline and bought a moduel for it it bout 30 pretty easy to fit and did what it said on the tin.. felt more power that made clutch slip a little and once got average millage up to 70+.. So this time i have a eos its done a few miles 150k but engine seems fine with lots of stamps in book.. Should i get another one of those moduel things or a chip type of thing or a remap could i combine any of them for more power?
Piggy-back modules just fool the ECU into dumping more fuel than is actual required for a given airflow. Mapping is your best bet.
Thanx guys best save some more pennies for a remap.. What gains can i expect to see? I always thought that module was coning the ecu the engine was cold
They may well do that as well, but the end result is the same; more fuel than is actually needed, resulting in more power, but its a cheap and dirty way to do it. You don't say which PD it is (115, 130, 150, etc), but typically you'd be looking at a 35-40bhp increase with a generic map, or 45-50bhp with a "live" map. Torque is the big gain though. Could easily see 300-350lbft depending on engine/map type, and then your into clutch-slip territory. Expect to pay anywhere between 250 and 400 depending on who you go with/map type.
Ah.. what makes the modules a dirty aproach? I liked the extra mpg will i see gains with a remap.. Still unsure weather to be greedy as of the high milage.. The engine btw is a 2.0 tdi 140bhp in an 07 eos
Its "dirty" because simply over-fuelling with disregard for other parameters is not conducive to engine/component longevity! Mapping alters all parameters to achieve "safer" power increases. Remember engines can always produce more power than provided as standard, because the manufacturers peg them at a desired level. Mapping unlocks this potential. A 140PD should map to 180bhp fairly easily. Any more and your looking at hybrid turbo upgrades.
