Help Does this look ok
this is from a 3k to 8k pull I did last night but it's typical of what's happening. Wanting to know if the maf readout looks ok as it seems to jump around a bit. Car is stage 2 p&p manifold, jhm tune, caf, with a recent carbon clean and a custom 2.75 exhaust. Seems to me like the maf g/s keeps dropping then rising again as it goes through the revs, is this the norm? thought it was a vacuum leak but tested it and can't find one anywhere yet, tried a different maf but got the same results. Read somewhere that it happens with the sw0080 software but not sure.It's really bugging me and hope a brain on here can point me in the right direction before I lose all my hair.
Thanks

sw 080 has the bouncing maf - sw 090 has a filter to make it look smoother.
your airflow is average for a 380ps car - but high timing at 36/37 degrees - depends how much it is ignoring knock sensors at that airflow to actual power numbers. you need to log knock voltages to see if it it running too much timing for the airflow.

Re: Help Does this look ok
I think I need to bring it to you Doug, with the mods I've got I was expecting more than 380ps
Re: Help Does this look ok
Booked in for Monday morning, health check and more than likely stage 2 map 4 years of ownership and thousands spent on mods I've finally come to my senses and got the mrc treatment booked. Car has every stage 2 mod with recent carbon clean and full 2.75 exhaust. won't mention the current tuners name yet but will be interested to see how they compare on the dyno and on the arse cheeks
Re: Help Does this look ok
i spent money elsewhere before I saw sense and got MRC to sort it out, needless to say, whatever the figures say, it's how the car drives and for me it is now noticeably different to what it was!

Re: Help Does this look ok
You already said jhm tune in first post. Oops
Re: Help Does this look ok
Yeah noticed that, oops indeed. Anyhoo im not wanting criticise any tuners, just interested to see the difference between maps, and most importantly get the car running as well as it can. My guess is there's a vacuum leak somewhere. It's just nice to have the peace of mind knowing its in the best hands possible. Hoping for figures North of 440hp as it's got the mods to do it

Correct me if I'm wrong,but I bet it's AMDBooked in for Monday morning, health check and more than likely stage 2 map 4 years of ownership and thousands spent on mods I've finally come to my senses and got the mrc treatment booked.

Re: Help Does this look ok
Ok i need to read back, it's had a JHM tune, your be pleased you finally took it to MRCCorrect me if I'm wrong,but I bet it's AMD
I did the same with my old car, it was night and day better afterwards
Re: Help Does this look ok
I honestly can't wait! Spent years reading other people's tales of pilgrimage to the hallowed mrc But being a tight arse northerner (stupidly)I couldn't justify the travel/time involved, until I got interested in logging and realised something wasn't right, I've run out of mods to do (apart from a charger) so this is the final modification to make the most of the car, and to make sure it's as mechanically sound as possible.Just kicking myself that I didn't do this years ago. Never dyno'd it before either so it'll be a fun day. Just out of curiosity were you running a jhm tune before the mrc one?
Re: Help Does this look ok
I had mine mapped at AMD and some other work done at a different company, I had the stage 2 map done with the stage 2 ported manifold+ JHM inlet spacers and gutted cats!.. I already had the cold air feed done before taking to MRC, I also had an itg filter, the MRC map is great!!
I'm sure you will be pleased
