I finally decided to get my Bluefin tested which i've had on since last April.

 

Whilst it is an improvemnet over the stock map, i always felt it should have been quicker and had more oomph than it had.

 

I took it off because the MPG suddenly dropped so i wanted to see if was that causing the problem and whilst the stock map improved things it was still low. Motorway runs were fine, but around town in relatively free moving traffic i was lucky to average 20 MPG.

 

I then had the engine Terracleaned for £110 and that improved the MPG to around 23 MPG average so before i put the Bluefin back on i decided to get the rolling road done.

 

The figures speak for themselves.

 

The official Ford figures are approximately 217 BHP and 236Ft. lbs or 320 Nm 

 

My tested stock map gave 202 BHP and 253 Ft.lbs 343 Nm, the tester said that was quite good because there will always be a loss from the engine to the wheel and anything less than 10% is good.

 

My Bluefin run was 217.5bhp and 276.5 Ft.lbs., 374 NM I couldn't bellieve it when i saw it.

 

Bluefins figures are 260 BHP at 5760 RPM (mine had already peaked at 5000 RPM)  and 406 Nm.

 

I was getting 15 BHP and 21 Nm more than i had before.

 

So basically the Bluefin gave me a bit more torque but is still well down on power.

 

I compared their chart to mine and it is nothing like mine.

 

I intend to ring Superchips in the next day or so.

 

Feel free to comment with suggestions etc.

Surely there's a lot of variables i.e. Engine condition spark plugs/gaps, fuel octane

HH,

i accept there are a lot of variables, but  I'm only losing 15 BHp on the standard Ford map.

 

Bluefin claim a 49 BHp increase, i'm only getting 15 BHP from the remap, admittedly more torque, but even so still way under what they claim

Hi

If you noticed a drop off in performance/economy, there may be a fault holding engine back.

Perhaps check with Superchips they should have a knowledge base on this engine and be able to point you in the right direction.

What brand and type of fuel are you using, and any other modifications?

 

The fuelling for the stock run looks lean to me, I'll admit I'm more used to seeing Jap Turbo dyno's but 14.7:1 on boost at full throttle would worry me.

Mark,

 

i use standard unleaded from Ada or Sainsburys.

 

What do you mean  "The fuelling for the stock run looks lean to me"?

 

Have you ever had yours tested on a road, if so what are the results?

 

I've sent the graphs off to Superchips and i'm waiting for a reply.

I've not had mine tested as still tinkering with the intake pod filter.

 

First thing I'd suggest is switching to a super unleaded fuel as I'm sure I've read somewhere that the ecu will increase it's ignition timing to make use of the higher octane. I know going to BP Super resulted in mine being a lot smoother and a lot more eager to respond. Which surprised me as with my previous car BP Super made it run like a kangaroo, not the speed just the jumping around.

 

If you look at your graphs, there's a Lambda reading, on the stock graph it's holding an afr of 14.7:1 which is what I'd expect at idle and cruise as it's the most ideal mix of fuel to air. On boost with the accelerator floored I'd expect to see it in the 11.5-12.8 range which is rich as the extra fuel (which is unburnt) is used to help cool cylinders and prevent det occuring.

 

Now it may just be that I'm used to jap tuning and without seeing other fuelling graph's I wouldn't draw any conclusions. The stock fuelling has been fine for years on the car's so it's more likely just my interpretation of the number's.

Mark,

 

good point re the super and the Lambda reading. It's something to consider.

 

Thanks.

 

As i said i'm waiting to see what Blufins response is and i'll update you all.

Here is Bluefins response, - basically saying there's nothing wrong with it because they take their readings at the crank and not the wheel.

If that's the case then the original Ford map should be a lot lower.

They also sent a test they did to show its measured at the crank and the difference at the wheel.

I would guess most people think it's power at the wheel rather than the crank.

"Is that all you were given is just peak figures? There is very little information to go on but keep in mind the figures you have been quoted are not a direct comparison for what we or the manufacturers use.

The power figure you have been given is at the wheels rather than corrected back to the flywheel based on the losses in the drivetrain and as such cannot be compared to the figures we quote. Think of it as being like comparing net and gross figures on your payslip.

I have attached a copy of a power curve from similar car to this email which shows wheel power figures on our dyno but please note the peak power figure quoted is the corrected figure calculated for the power at the flywheel, just like the manufacturers use. "

I'm pretty sure there is an underlying problem with your car. You need to get that resolved before attempting to Bluefin it.

In standard trim(without Bluefin) You only get 202Bhp (this is the corrected value at the crank) the wheel bhp is 171 according to the numbers you provide on the 2nd pdf.

You should achieve around 215-220Bhp i standard form, if the car is behaving as it should.

I think there is a leak somewhere on either the vacuum or the boost side. The boost solenoid is known to cause problems, so I would start checking if that is OK.

As others pointed out, and AFR(AirFuelRatio) of 14,7 is too lean at full throttle. I think the eginemanagement recognises this, at reduces timing/boost etc. to spare the engine.

Have you had fault codes read out?
