Who has had a remap!

[shimmy]

Not a poll this time but interested to know who has had a remap and who has genuinely felt a difference or improvement

I have had two on my CSL. First was with Simtis and te car definitely felt better at mid range power, mpg improved and there was a more even throtle response. Interestingly it was put on at lunch time at a track day at Donny and i could easily feel the slight improvement by the end of the day. Even more noticable on the drvie home BUT no big difference just minor changes you could pick up.

second oen was a Simpsons/ESS map which removed the limiter and gave memory to the sport button but otherwise felt no difference. On checking it seems as if the only other change to the map we could find was a slghtly increased rev limit by 150revs.

With my plans this year and the exhaust and header mods as well as weight loss i am planning a visit to get a custom map for my car just to trial. Plan would be to give it a go on my car as it is then remove it again.

Then later to put it back on with modifications for the headers, cat and back box to see if we can get some real gains (although i understand they will not be large). My hopes are that we can get say 20-25 bhp. I would be happy with that but i know looking at history of maps on M3 and CSL it is unlikely.

I was planning to get some high lift cams but until i can fidn soemone confident with remapping for these i am a bit hesitent

What are your experiences?????????:smokin:

I had a custom map on mine before Shimmy, and it felt better (slightly) at the time but I don't remember it being mind shatteringly different, unlike the diesel tuning boxes. I did have better cams on it but dont ask me which ones :hahaha:

Actually scrub that I know they are Schricks, just don't ask me the numbers as I've no idea! :beer:

[shimmy]

unless you go for the full race cams which are not recommended on road cars, the only Schrick cam ssem to be the same profile 188/180 but high 14mm lift!

it seems the mapping for these to gain the bhp runs the risk of hitting pistons/valves if you dont get it right!

seems custom mapping is the key but nobody is very good at it!

I think Thorney use superchips??, I dont know if they are fine tuned on the dyno, I hope so tbh as the price is not cheap so dont want some sheeite generic flash on map. But im getting a carbon airbox with maf delete and headers like you, so its an alpha N map so I suspect it will be custom. One things for sure I cant wait for it to be ready, :drool::drool::drool::drool::drool:

I know where you are trying shimmy, heard good things on Cutters, but generally the guys on cutters are just road cars so placebo effect takes over and they dont seem the most clued up on average, not a dig at them, just my take, on here most are out on track regular but majority on cutters are road cars. Ive also heard a few things from my sources that he is not the most clued up, but in the tuning world, things are said from other tuners about other tuners that you take with a pinch of salt.

Let me know how you get on shimmy.

know what you are saying but even the best do very little and he does take the time to explain what he is trying and show you where and how

even spent 2 hours with me analysing every change the ESS map had made to my car....didnt find many;)

he may not be a long standing race mapper but he is smart and sharp and willing to give it a trial before the headers go on,

most fo these maps are standard ones for certain mods on the e46. As there is so little gain there is very little money in the e46 so very little investment of time

im sure you will get a map for your car in its new state but i doubt if comes with a guy altering the software as it is put on but thats the nature of the e46 situation i am afraid

I know exactly what you are saying Shimmy, He does sound ok, esp if he is making the effort and trying. Thats why my comment about taking what people say with a pinch of salt was made.

I have done a before run of my car on the dyno, so Ill know what improvements and where, have been made with my upgrades and map?
As soon as it comes back ill run it on the same dyno straight away to check the map out and see where the improvements have been made.

I am also going to run my csl back to back with my M3 to see how they compare, standard CSL vs modified M3, ill post up all graphs on here and give my opinion.

Let me know how you get on shimmy. :thumbs:


My last M3 that i sold before christmas had an amd map on it, it certainly pulled well, but I felt the 4.10 diff in that made a big difference, I think the diff will be your favourite mod.

[shimmy]

you could be right about the 4.10 diff, as loking at the figures it will suit a number of the UK tracks - just not convinced it is geared anybetter for Spa!

but the SS race back box is bound to make me smile as well!:thumbs:

i have been a big advocator os the good looking 19 inch rims and cups but i wonder if ill be able to sell the difference with the 18 inch rims being stiffer & lighter with 18 inch Cups. that will be an interesting one

after all that i am quite prepared to admit that it wouldnt surprise me if after all this the dyno is no improvement, fuel economy goes through the floor, and lap times get slower - stranger things have happened!

[DazBlackCSL]

Mine is Mapped, was done by thorney last year ish, not been on a dyno so no idea about numbers etc, dont really notice any diff TBH ..

Does pull slightly better through the mid range over Rob's / and a mate of mines but not enough to warrant the ££££ really, was combined with a full system though with 100 cell kittens .. mix of Miltek and SS.

Nicer noise tho, and better looking tits :whistle:

Sods law means you are probably right,

Will be interesting to see what they go like. :thumbs:

We custom map all the cars we remap, there are different levels for different mechanical differences. A stage 1 file (standard car) is more about how the power is delivered rather than bigs gains, stage 2 (full exhaust with cats) is a bigger jump and we make much larger changes to fueling as the airflow is increased. Stage 3 adds the manifold which on its own adds 8-10bhp so we again make larger changes to fueling and timing. Stage 4 adds cams of which there are three different versions from Schrick which need different options as regards rockers, retainers etc. You cant fit cams unless you map the car to suit or it will run lean.

The maps are quite different to M3's due to airbox. Superchips is our mapping partner but all the maps we do are ours only and custom done on the dyno.

Race car maps are a version of the stage 4 although we move the torque range around depending on what we want, on my race car last year we tried about 6 different maps some with high end power (start of the season) and latterly with more power lover in the rev range (we disigned the manifold to achieve the same thing) and the result was a quicker car and lower lap times.

Thus far we've mapped/upgraded nearly 130 CSL's in the UK, and if you dont like what you get I'll take it off and refund you.

I assume you have mapped after uprating cams from CSL 288/280 to either 14mm lift 288/280 or bigger cams

What do you do about mapping to make sure pistons/valves dont knock?

The higher lift cams need to be fitted with new retainers as well as rockers. Its what raises the cost so much.

Im sure Ill be more than Happy John:drool::drool::drool::drool:, so dont think it will come to that.

I just cant wait to get her on track:smokin:

PS you got some more pics for me.

and at least one in France too.... mine...:thumbs:

[Thorney]

and at least one in France too.... mine...:thumbs:

Hello David, didn't know you were on here? Hows the car?

Not at work at moment but from memory we have:

3 x French
2 x German
1 x Sweden
2 x Swiss
2 x Channel Islands
1 x Greek
2 x Portugal

I think thats it.

Done a few remotely to Hong Kong, China, New Zealand, Australia, SA but a lot of that depends on how good the local dyno guy is in making required changes to the maps (that we need to do here) and the quality of the local fuel.

What do you regard as a custom map? When my stage 2 was fitted we run out of time at the end of the day and you put on a map you had. We didn't have time to run my car on the rollers to check everything. But all seems good and i'm happy with the car!

[Thorney]

Yeah I remember, we did a couple of adjustments but ideally I'd like a final dyno run on it. Sometimes we do run out of time but thats why we really say we need the car for a full day.

[DazBlackCSL]

How much of a difference does the dyno make then ... ?

Rich just put mine on over at the Race Wkshop so no Dyno solutions on mine

A custom map is a map which is tweaked either on the road or dyno. If no road or dyno then they were just a generic map to suit your stage of tune. Most maps are done this way.
A custom one is a generic map that is flashed on and then certain areas are changed accordingly. This is the safest way and best way to tune.

A run on the dyno may not yeild any more power that is truly noticeable Daz, but it will show how well/ bad your car runs with the map. It can highlight any fuelling issues which can duly be changed.

IMO a map is only deemed safe when it is checked on the rollers/road, the dyno is a tool, not always for power figures either.

Im not saying lots of testing/research does not go into flashed generic maps, as most of the time it does, however there are some very crude flash maps out there. But every car is different so a custom map is better every time.
