Crazed A Tale of Remapping

After mild pressure (!) from Vic at Sunnyside I finally gave in and took my 20v in for a re-map, they work with Gus and use his maps. The car had been mapped at some point and was putting out 188 bhp and 330 ft/lbs of torque; some say this was a strange combination.

I reasoned there was something amiss as she smoked excessively both on the over-run at low speeds and when booting at all speeds; at times it resembled a destroyer laying smoke and could be embarrassing. She also hesitated and often surged at low speeds, not badly but enough to spoil the drive.

I also couldn't get more than 45 mpg even after 500 motorway miles at 70 ish with cruise control engaged. Is that ALL I hear you cry

4 hours later I got the call from Vic.

They had sent the map to Gus and his quote was "It's the worse I've seen in 25 years", that may have been a slight exaggeration, but you get the point. The really bad news is that the new map couldn't be written to the CPU. The only answer was to send the CPU to Gus and for him to work his magic; starting from scratch and then writing a new map over an original. I decided to go for it; that was last Thursday.

In summary, the old map raised boost at low revs and reduced it at mid to high revs; not quite what you want. Whoever re-mapped the car had delved into depths that should never be explored, that is why she couldn't be re-mapped and had to undergo the surgery.

I have contacted previous owners apart from the deceased second owner, and all have denied knowledge of the re-map; and I believe them. I can't contact the second owner to find out who did the re-map; I believe he ran his own racing team, if it was like the map, no wonder he is no longer with us.

I collected the car today, Tuesday, what is she like?

In a word;


FANTASIC


A word of thanks to Gus and Vic from Sunnyside. It was expensive but it was worth it, if I get an extra 5% fuel economy the work will have repaid for itself in 5 years absolute bargain

The moral of the story?

Look before you leap, particularly into the black art of diesel re-mapping.

Trust no-one other than those that are trusted.

Seek guidance and advice from those with experience.

Sod the cost, an Alfa is for driving, so why not enjoy the experience! And 218 bhp certainly helps

Hi Toxic,

That sounds like a good outcome and is making me even keener for tomorrow to come round.

My Brera is booked in with Gus, who is opening early and then dropping me off at the train station, so I can get to Liverpool for an early meeting.

Not looking fowards to the meeting, but am looking forwards to the drive home

Hi Toxic, thats a massive improvement, and I bet its a smoother delivery of power too, like you say worth every penny.

Mr.Steeler your in for a great drive home but do try to stay focused at your meeting.

Steeler, when you are in Liverpool if you here a very loud noise it will be me going past in my 155, Gus has done two of my cars, not worth going anywhere else...

Absolutely, the way she picks up and revs is almost like a petrol engine, I'm having to re-judge the clutch / gear change it's so different. It does fly

And apparently it will get even better as the CPU learns my driving style.

Hello all,
Just a quick update before I head off the the beer fridge for a celebratory lager

Well I'm home with my remapped, DPF'less, EGR closed Brera and I've now got the car I wanted and hoped for in the first place, Thanks Gus.

These are my brief first impressions.
Bearing in mind I drove from Gus's place straight to the motorway, then down the M62, M1, M18, with very little urban roads / dual carriageways etc on the run, apart from a quick stop off at the gym, it's hardly a full review, but here you are:-

The car pulls harder and smoother from lower rev's, with more torque making the drive feel a lot quicker, and with a greater push in the mid-range also making the power very usable.

At motorway speeds it's far more responsive without the sluggishness / lag, you put your foot down, you go, and how

I don't know if it's just my imagination, but on the way back it also seemed smoother / quieter than in the way up at 5:30 this morning.

I'm really looking forwards to taking it down the roads I know to get a more direct "seat of the pants" comparsion against the pre-map car.

I did even managed to miss turn off on the way back, so did the blast to the next turn off and re-join routine, and lucky for me the slip road was empty of cars so I managed to give it a bit of a blast in 2nd, 3rd and into 4th, very impressed with the outcome, its going to be a deceptivley quick car to drive, better get some practice in.


Thanks to Gus for his time, work and the taxi to and from the station. It was nice to put a face to the voice at last.

ps ta for the nice "addition" in the rear window, I saw it when I filled up, with Shell V Max, and did smile to myself.

will post more info after while if people would be interested?

Cheers, Pete

p.p.s, didn't hear you wayne-dear, but maybe next time I'm over that way. Just how loud is the 155?

Was a similar story with mine Toxic.

Previous re-map was smokey and crap, the Gus re-map is in a totally different league!

Worth every penny.

And that must have been a considerable "penny", all the way from Yemen.

Whats your torque figure now TOX1C ?

I d expect approx 330 if your car makes 215 brake, but seeing as it was making 330 anyway, looks like it should way more now !

I don't know, but there are quite a few torques. On a familiar road tonight she accelerated like never before with a big dose of torque steer - never had that before at that point so the figure must be as much if not more, but it's more distributed and I reckon higher up the rev band.

Figures are irrelevant - so I'm told; it's the way the car drives that counts. But I would like to know.

We just need someone to try it.. Won't be me, if/when I get a 20v I'll dump the F40 box, the weak driveshafts, the £800-to-replace dual mass flywheel, the stupid concentric slave cylinder set up and fit a good old reliable 1.9 16v box, some 2.4 10v driveshafts and space my wheels out a little to accommodate it. Then I'll stick in a Q2 for good measure

Actually yes, but the F40 in question was out of a 159. It is much shorter. But I know the 1.9 6 speed fits on a 2.4 10v so fitting it on the 20v won't be an issue either

Sounds good, but wont the 6 speed eat into the passenger footwell cos of the wider 5 cyl ?

(thats what you said not long ago, lol)

Passenger wheel arch, yeah it does protrude a couple of inches more, but its not too much of an issue, can be sorted by wheel offset or spacers. Block and crank is the same, they have some differences but nothing that is insurmountable. Its more the re-doing of the clutch hydraulics that bothers me but everything can be swapped over from the 10v. The shifter and linkages too are different too. I'd like the 1.9 16v box but would fit a 10v 5 speed box if thats all I could get hold of.

Anyway this is off-topic now, back to remapping.

Ok dad ! - maybe start a "JTD 16v F30 box into 156 20V thread" to continue discussion ?

Waiting for the torque figs ! . . . TOX1C needs to get it on a rolling road . . .
