JB4 info and discussion thread

[mw1978]

Thanks Oli
I will try and let You know...

 

[OliS3]

I went for my dyno run today and I had a fantastic day and my ears are slowly recovering

The car made 367hp at the fly, 328 wheel hp and 368 Ib/ft. For £400 and some help from George i'm amazed!

Run 1 - Map 6 (Good ING advance, IAT weren't too high)
Run 2 - Map 6 (ING advance dropped to below 5 as IAT was climbing but still made best power?)
Run 3 - Map 4 (should be stock but it works out at 325hp fly?)
Run 4 - Map 6 (IAT was very high, still a good result for a heat soaked car)

Thanks for sharing the results Oli! Was your car stock? Funny that map2 gave more power than more aggressive map6..

In order of runs

 

[mw1978]

Which gear was use?

Nice!

How was it again, is your car completly stock besides the Jb4, or does it have slight hardware mods like intake, inlet elbow, etc?

The 325 on map4 is a bit odd I agree (unless you have full bolt on mods). Didn't think the Jb added any boost there. Wonder what George says...

 

[Salik Sajid]

There's no map 2 runs, i wonder why u didnt we cud have compare with map 6 runs. Anyway those are impressive runs, u need some more bolt-on mods to support iats.

4th gear on all runs

Run 1 - Map 6 (Good ING advance, IAT weren't too high)

Run 3 - Map 4 (should be stock but it works out at 325hp fly?)

I've pulled the snow gate out the air box and the exhaust flaps are open, other than that nothing else

I'm glad someone noticed I didn't run map 2. Originally I had 3 runs so I wanted to do 2 runs of map 6 and a stock run which made sense. Anyway he let me have another run but I never thought to use map 2 which maybe I should have but my car feels so much stronger on map 6 I've never looked back and thought to try map 2 again.

Agreed on the mods but i'm trying to behave

Good example that you read what you think.

That's really impressive I think for completely stock esentially.

I think so, seems like the best bang for buck mod anyway

Can you share your map 6 settings?
Keen to compare to mine, which are below.
I'm doing a dyno day soon and will post my numbers.

That's interesting as I found map 2 a bit too aggressive as a daily drive, hence George helped me with my current map 6 set up. I'm getting high 3 second 0-60 times with the following mods on map 6.
BMS Intake
BMS turbo inlet elbow
BMS turbo muffler delete
GFB DV+

Agree that the JB4 is great bang for buck !

I'll run your settings this week and report back

My settings

I got r600 intake. Fuel vpover nitro 100
FOL 60 but I got error code when scanned 3AD2 which is fuel rail pressure low. That's very weird because I have not seen check engine light

That's not so unusual.

Got that code a few times with Jb1.
After following George's recommendation, avoiding full / high trottle with less than 25% gas left in tank, I have never gotten it again.

If that's not enough, lowering FOL to 50, or 40 in some cases, usually helps.

I'm not sure you'll like my settings if you found map 2 too aggressive but still worth seeing what you think

 

[MartS300]

Impressive results.. would have loved to if seen a map 2 run for comparison

Today refilled gas and did few WOTs. No error codes!
Thanks again

You can use either the value you want over stock ie +5psi or the value you'd like the car to reach ie 20psi

If you use a number under 10 it's additive; 10 or over and that's the exact PSI the car will try to reach (absolute).

What you should do is switch to map zero or four and do some runs and then we can compare...
