LCR rolling road done today...disappointing and scary news!

[rickyjones1209]

Got the motor on the rolling road this morning to see how the car is running. i had a receipt from Raceevo uk when i bought the car showing 260bhp but no graph. i have since added a catback exhaust, dv and k+n. i didnt expect this to increase power only set me up for more mods.

anyway, the after 1 run on the machine the guy came off looking concerned. the graph showed 242bhp and 286lbft. from the look on the graph it comes on boost very strong at 3-3.5k revs then just levels of and doesnt do much.

not the power i was after but i wasnt expecting stupid numbers anyway. the concern is that apparently the car is running very lean ie not enough fuel which can lead to blowing my engine up. the guy made out that after a few laps on a track he'd expect the pistons to melt! he has told me to drive off boost where possible until i get it sorted. i wanted to get a stage 2 map or live map after a few more mods anyway but means im goin to have to dig deep to get it all done in one go.

i'd planned to get dp and decat and TIP then map again. would you think this is a good idea? any other suggestions?

anyone used Raceevo before? anyone know why it could be running dangerously lean?

Not enough fuel could be blocked fuel filter, knackered FPR, on it's way out fuel pump, blocked injectors.
As he advised, stay of boost

 

[DPJ]

Failing MAF.

Poor mapping.......

Take it to AmD essex mate i had a similer problem my pistons shrunk due to someone cooking the engine,the water pump was broken whitch caused it, i had to have a full engine rebuild,not cheap but now shes a beast.

 

[Rocky Rocastle]

AMD is a bit of a drive from up here, for a second opinion mate go somewhere like Votex in Congleton

so is it worth checking these first? can i check these parts to see if they are ok or would it be a case of replacing them all?

whats FPR? fuel pressure regulator?

could vortex check these out for me Rocky?

dont want to be adding more mods then live map if i have something else causing the problems.

 

[LEE69]

Yeah FPR is fuel pressure regulator.
Get these checked out, and the MAF before going forwards.

log your own lambdas reading to see if it concurs
031 on vagcom

 

[Rocky Rocastle]

yes mate i would of thought so, Votex is a vag specialist who's a sponsor on here (i think). Revo dealer who's good with a laptop so if you stuggling he should shed some light it for you unless as stated you can get vag.com, I haven't got it meself though soz mate

I have heard the water pump is notorious for failing, what are the symptoms of it? If it ever happens, i'd like tp catch it before any damage.

just replace the water pump with every cambelt change! its like £40 extra i think i paid!
as for running lean...
fueling is computer controled and not adjustable by a dealer etc. i'd suspect maf if you've fitted a filter (oily ones kill the hot wire) or fuel pressure - change filter and get it mapped propperly
get someone propper to do it like #REVO TECH# they've done an awesome job on my stage 2! really cant complain!
good luck with the problem chap!

 

[rickyjones1209]

the plan now is fit dp and decat (on order), fit ths TIP (also on order) then get an APR stage 2 map by awesome GTI. getting parts fitted at same tame as 60k cam belt change next couple of weekends so i'll get water pump changed and fuel filter changed and hopefully after map we should be all good.

how can i check the MAF though or is it a case of replacing it?

 

[vee_dub_modder]

VAG COM is best way... or swap it and see if it improves?? but you prob cant tell without rolling road/vagcom anyways

 

[Rocky Rocastle]

think I saw you on Saturday Ricky near the retail park, i was in my LCR

 

[ibizacupra]

have you had this verified and logged yet?

throwing money at parts otherwise blindly

 

[rickyjones1209]

not done anything yet. got parts on order though as they were going to be ordered regardless.

when they are fitted goin up to awesome gti getting it on vag com see if is anything else up and get stage 2 sorted!
