CR170 Remap

[OLDOILER]

first 2 maps didnt work with the turbo pressure sensor parameters, just different maps in an older style 1 cable install

all ok, back to DTUK for new CRD-T software to be written to the box. 5 mins later we're back on the road testing out. again no worries.

third - CRD-T - Map
this, now using the turbo pressure parameters was more noticeable at all speeds but especially at 70+. didnt have the roads to try it but i suspect the 50-120 leptons/hr is vastly improved
lots of TCS light
thing thats got me wondering now is that circa £360 for DTUK box is very similar price to REVO when they have the £100 off discount running.
we'll not get into the "box is easier to remove" / "revo is safer/better/more powerful" debate....i just wanted anyone thats wondering to know my thoughts..

I'm running 3rd stage map and first stage turbo pressure increase [that being the setting that achieved 210/423 in DTUK tests on a CR170 engine]. I’m interested in the comment that Andrew had to modify map/pressure profile though - will have to talk to him !!. The main reason I went from ECU flash to tuning box is my past 4 VAG cars had been flashed at a cost of £xxxxx and if I'm changing cars this frequently I might as well go for a tuning box [which bear no resemblelance to the early designs] AND I do not do track work anymore so do not need the enth degree in power, just good touring performance. The one issue I do have which Andrew has NOT sorted is a delay at around 1.7k - 2k rpm where there is a lost of power coming out of a bend [ this does not always happen, and is after throttle off - bit like the DSG s/w error!!]

Martin tried 4 maps

First of all the system was not running turbo pressure sensor software, so in essence was a CRD2+ module, when he came back i reflashed the module with common rail + turbo pressure sensor software, thus making the system a CRD-T

The last file Martin ran was map 3 plus 1/10% which is what we recommend.

a few of the guys over on Scirroconet.co.uk are using the CRD-T's on their 170's and again using map3 + 1.

sorry about delay in response! was a busy afternoon/evening yesterday after a trip DTUK then getting our 2 niggly boys into bed...

so, after REVO's response i was happy (well, happy enough) to try DTUK box.
Andrew was all prepared and had his guy fit the cable to the leon inc. the cable to the turbo pressure sensor.

first run was with software that was only a small % increase in bhp/Nm just to see how the leon reacted.
it drove normally no problems or errors.

quick stop and flicked the jumpers on the box to the 2nd map - bit more bhp/Nm - all still ok.

how did it drive?
first i'll say that the local roads to DTUK we're soaked and it rained all the time.
first map -couldnt feel any difference, small flicker of traction control light

second map - just noticable improvement, mainly at say over 50 leptons/hour. especially noticeable pull at over 70 leptons/hr, lots of TCS light out of juntions

third - CRD-T - Map
this, now using the turbo pressure parameters was more noticeable at all speeds but especially at 70+. didnt have the roads to try it but i suspect the 50-120 leptons/hr is vastly improved
lots of TCS light
difficult to gauge just how aggressive it due to losing traction so much.
i think it would have felt pretty angry in the dry.
my other thought is the DSG smooths out the power delivery nicely (standard and with box fitted) so its difficult to feel the pace of the car truely until you read the speedo

i had them remove it from the car as i wanted to think about it for a bit.

thing thats got me wondering now is that circa £360 for DTUK box is very similar price to REVO when they have the £100 off discount running.

ps volvo seems sweet, smooth addition of power, not aggressive (doesnt want to be, its the family wagon/caravan tow bus lol) and the run home returned 45 mpg which is about 10% better than normal on that type of journey.

That's the way i'm thinking at the minute, i can't peel myself away from wanting a remap instead!

I've been reading Briskoda lately and the praise the CR170 gets with a certain remap makes me want to try out a truer (so to speak) way of tuning my car.

You know ill look after you the Leon is. Great car, but so much better once it's tuned , add a pedal box too and it's rather good

not to hijack this thread but are your pedal boxes like those horrible sprint booster that ruin throttle control etc?

I DONT THINK THERE is any odubt over these DTUK boxes making more power/torque. i towed caravan last nite for the first time with the box i got fitted to the XC90. the volvo definatley pulled our 1400kg caravan easier. its not blinding performance but then a 2 ton plus vehicle isnt gonna be transformmed by only around 25-30 bhp, but it does give the towing ability that bit more.

as for the leon maybe its the dsg. we have no proof that my gearbox 'allowed' the extra power. it maybe did. it maybe didnt.
maybe it was the wet i experience that blunted the effect. who know's

Whenever tuning later diesels equipped with DPF's, its important to log test and adjust the ECU on the dyno.

DPF sensors should be logged along with EGT's to ensure a) the DPF is not struggling with the fuelling increase and b) the turbo is being kept safe (i.e. not exceeding a certain EGT)

Tuning is not only about extracting peak figures. Alot of maps require adjustment to ensure that power delivery is extremely smooth. Both the 170PD and 170CR tend to have 'holes' in delivery at lower rpm's.

With regards to the DSG, again, torque limiters within the ECU have to be accurately adjusted to ensure delivery is strong and smooth.

DieseltuningUK, the following was what I have experienced using the your module " Alot of maps require adjustment to ensure that power delivery is extremely smooth. Both the 170PD and 170CR tend to have 'holes' in delivery at lower rpm's" - from P-Torque UK thread That is what I get between 1.5 - 2k rpm and does not always happen @~! sort this issue and indeed you will have a comparable system to a re map. ..........................................

The system connects to the throttle sensor, and weve not had any negtiave feedback on them yet, infact several people tried them at Inters over the weekend and commented on how smooth the system felt.

A stage 2.5 S3 shaved 3/10 of a second off his fast 0-60 sprint, and 1 seconds off on the handling track.

Cant comment on the system youve mentioned, but we can control where and how we want the throttle to respond so can make it as smooth or as fierce as we want it.

I'll put my two cents forward here

I demo'd both the pedal box and the tuning box on the strip over the weekend and was very impressed with both, that impressed that I'm giving it some serious thought about buying one, only lack of money is stopping me atm.

First run down the strip without any of the systems on I got 7.56 seconds for my 0-60 and 16.179 for my 1/4 mile

The 2nd run, Pedal Box was fitted however I did bad as I missed a gear and posted a crap time but was still very impressed with the pedal box.

3rd run, we stuck the tuning box on and I posted 7.00 seconds for my 0-60 and 15.614 for my 1/4 mile run.

4th run with both the pedal box and the tuning box on I posted 7.05 seconds for my 0-60 and 15.527 for 1/4 mile run and I must say in the final run I struggled to keep the power down and the wheels were spinning in 1, 2 & 3rd but neverless the power output on both systems are so smooth!

If anyone requires proof of my times I will happily post up a scan of my results when I get home.
