I had my car remapped by Bob Rawle today and very happy with the results. It now pulls better in all gears, is loads of fun on full throttle and PPP exhaust even sounds better.

It's a MY05 STi Type UK with PPP fitted, the STi uprated panel filter, a set of NGK PFR7b’s spark plugs and a three port boost solenoid.

Graph attached

 

That remap I am contemplating feels oh-so-much more tempting now!!!

Don't have the special plugs or soleniod though.... and mines an 04.

 

nothing too surprising - Bob is known for delivering excellent results

 

Very interesting reading this.

In my experience a PPP MY05 STi Type UK makes 235-240bhp and 235-240ftlbs torque AT THE WHEELS using Delta Dash's Road dyno, and typically the STi with this much power will produce the following acceleration figures:-

40 - 60mph = 3.1 seconds
50 - 70mph = 3.0 seconds
60 - 80mph = 3.2 seconds
70 - 90mph = 3.5 seconds
80 - 100mph = 4.4 seconds

The same car then remapped by Mocom Racing, along with an uprated panel filter, 1 step colder spark plugs but retaining the factory 2port boost solenoid, produces 270bhp and 277ftlbs again AT THE WHEELS using the same DeltaDash Road dyno function under the same conditions on the same stretch of road.

Now what's interesting is the acceleration figures with this much power:-

40 - 60mph = 2.9 seconds
50 - 70mph = 2.6 seconds
60 - 80mph = 2.7 seconds
70 - 90mph = 3.0 seconds
80 - 100mph = 3.6 seconds

Those acceleration figures match the figures stated in the original post at considerably less quoted flywheel power........

I suggested somewhere in the region of 310-320bhp and 315-325ftlbs on the aforementioned STi using a correction factor of around 16%

Why did I choose to apply 16%?

After a visit with the same STi test car to a number of rolling roads a couple of years ago, I decided to add around 16% to the wheel figures produced by DeltaDash - this would guarantee that the figures produced on the lowest reading rolling road would match the figures I quoted and all else could perhaps produce a little more The last thing I'd want is a customer coming back with an underperforming car

This is in no way taking anything away from Bob, he can only extract the power from the car that the sum of all parts can produce and this is something we, as are all mappers, restricted to - there's no magic formula if the mapper knows what they are doing.

 

He did mine as well yesterday. Interesting driving in the conditions while mapping! Usual thoroughness by Bob and pleased with following results-

Thankyou for making me feel even better about the remap i have booked with Bob, ive heard loads of excellent feedback about him, i cant wait to get my MY99 UK Turbo done!!!

 

You must have been after me ... I caught some heavy downpours just after heading for home ... not really ideal mapping conditions when you only have 20m visibility!

Not really too bothered about the figures anyway, more with the way the car feels and the shape of the torque curve; but it's interesting that there isn't a standard value for the % of transmision loss based on model year.

 

I've been thinking about getting mine remapped, do you know how much Bob charges for a remap and does it differ from mapper to mapper?

Mines an 04 STI with PPP

 

Remap was £640 incl VAT. Yes, it does differ from mapper to mapper, but not by much ... you are probably looking at a range of £550 to £650 for a Ecutek remap (you pay for the license and remap the first time, but any subsequent remap would be about £300 less) and it is worth the money IMO; especially if you already have the PPP.

 

Hmm i have an 05PPP currently mapped to 330bhp and 300lb/ft

Would the parts mentioned and a another remap make that much difference?

Can anyone supply a link to STi uprated panel filter, a set of NGK PFR7b’s spark plugs and a three port boost solenoid.




Thanks.

 

If you are already at 330bhp, perhaps you should look at making some additional mods before having a remap.
Spark plugs I got from Sparkplugs.co.uk or something like that (about £40). Bob supplied and fitted the three port solenoid (about £150) and STi uprated panel filter (about £70).

 

not the smoothest of power curves but a good increase over standard

 

As far as I know, any road dyno graph will look a bit spikey like this because the ECU is busy with other tasks under full acceleration and has less ECU time to dedicate to logging.

 

Are those 3 parts worth doing with out a remap??

 

Then the ECU needs upgrading if it can't register the parameters quickly enough
Here is my power graph for my home built Cosworth Motor on 95 Ron fuel, should be 450+ on Optimax

 

Not really worth it unless you're running over 1.4/5 bar boost. It just helps boost control.

 

Struuuuuuuuuuuuuth , thats some lag....lol
T4...?

 

ROTFLMAO

 

Only the STi panel filter

The plugs are only required if running higher boost pressures and the 3port solenoid allows for 'better' boost control if mapped with Ecutek.

 

The Subaru ECU is far better than aftermarket ECUs, the curves produced from the Road dyno function aren't smooth due to the sampling rate used in the software - stick the car on a dyno and the curve would be smooth with a nice wide powerband

 

Sorry to hijack the thread - quick question though:

I had my car remapped (ECUTEK) about a 15 months ago, if I take it to another mapper how would he know I had an ECUTEK license already? or would I have to take it back to the same place.....?)

Darren

 

.................................................. .......

 

Just a quickie where is Bob situated, any other recommendations?

 

You can take it to an Ecutek dealer of your choice , as they go to program it they will see that a licence is already in there.....

 

Whats the standard boost on an 03 sti ppp mate ?

Would I need plugs If I get Andy Forrest to remap the car with ECUTEK ?

I was planning just to buy that filter off you and away I go.

 

Bob is mint, he's mapped mine a few times now and each time he's helped with the odd issue (nothing to do with Bob's work, more to do with previous work done on the car/parts and bad mapping). He's given so much advice I can never thank him enough for it...

That Scooby "abuser"s map is interesting...wonder how my car will do faced with a motor that makes 100 bhp at 4000 revs... lol
A m8 of mine, JJ in Exeter, has a Cossie with approx 400 bhp and his pulls very well from 3500 with a big hybrid turbo - think someone needs more boost control?

I need to visit him again early next year to fit a motorsport fuel pump as my uprated pump just isnt upto the job, drops pressure from 5500. I expect bob will pick up a few more horses from my motor as he did with the warranty replaced actuator ("old" one cracked open at .7 bar, new one 1 bar - rated 1.2 bar). Harvey has also been helping with parts sourcing - tops!

 

Zak you need to quote weight and the gear used to put any credance to your figures as both will have a huge effect on sector times, 16% loss ... nope. I use 21.8 (22) % these days with an accurate weight, always the same stretch's of road for the power runs, that way my car by car database of figures is consistent and comparative. Rolling roads are a variable feast as we have all often debated and force = mass x accelleration is far more realistic.

bob

 

Likewise Bob, I run all cars (providing they are mapped from my base in North Weald) on the same stretch of road under the same conditions, all 5speeds in 3rd and 6speeds in 4th. And like I said I choose to add 16% because it matched the lowest reading RR from my testing a couple of years back.

 

That car must be a nightmare to drive on the road.
