Manic Stage 2
1 Attachment(s)
Hi, Had my N18 JCW mapped to Manic Stage 2 today, car runs a Airtec Intercooler, scorpion decat and AEM. It produced healthy figures, drives well and pulls like a freight train, but on the dyno the power graph looked a bit strange. Stock and mode A are a nice smooth curve but then B and C seem to be inconsistent up top end? Will be asking manic to see if they have any ideas but I was wondering if anyone had the same sort of thing or any ideas what it could be? Car has no faults codes logged, it did have a code for a valvetronic fault in the history but I’ve owned the car over a year and it’s never thrown a check light. Any ideas would be greatly appreciated. |
Did you change spark plugs to ngk 1422?
|
Yes, new cooler plugs where fitted just before the dyno run |
You might want to re-post your question here:
https://www.northamericanmotoring.co...ally-here.html There is a wealth of information about the manic tune there and several manic tuners who post there. It is your best chance of getting an answer to your question. |
stock clutch?
|
Can you data log? Timing, A/F, IAT, rpm, not sure what else would help troubleshoot with your manic dealer.
|
Hi, Yes it’s stock clutch, I will see if I can get the data log for the runs, they where recorded I just forgot to ask for them. But we did have a quick look through them and everything seemed to be where it should be in terms of boost, AFR etc. |
I tend to wonder if you’re maxing the turbo out ! Before my high compression rebuild I had the same problem then I started running a 47mm turbo with meth !!

Are those BHP or WHP figures?

Bhp figures, removed the diverter valve today and seems fine but will fit the latest revised valve anyway |
I agree with saying that your turbo is just maxed out. its just looks like the power is fluctuating. On Map A target boost is 18lbs which is easy for the S turbo to do. but on MAB B (20lbs) and Map C (21.5lbs) the S turbo has a hard time keeping up with that demand in the upper RPMS.

It’s a FJCW with JCW turbo. Got some graphs of the air flow and intake pressure, couldn’t get AFR but everything seems fine with that. |
I dont see any major inconsitencies.. looks fairly normal
