Someone was asking the other day if there was any smoke since the remap. Have not had the time to get the gopro out and go for a spin and check whilst driving.

So took a quick video this afternoon.

I rigged up my Contour pointed at the exhaust and drove around 10k, from idle and just revving I get smoke like you, when I pour the coal on early, say 1500 in 4th, it will smoke until the boost reaches optimum and the torque kicks in then all is fine, but, I have re rigged my DTRonic because most of my extras are wired in through the DT loom, tomorrow I'm doing a dive up through the mountains so I will get a good idea of fuel eco and EGT.

When I get back I'll remove the DT again and rig the camera up to see what happens, I may then need to cut into genuine loom to cut in my bits and pieces.

To sum up this thread. Have written up details in my build thread, but for those that don't read it, the whole ECU Remap is working beautifully, it is the icing on the cake for all my other mods. Torque is up significantly, yes there is some smoke, worse if you rev it a few times stationary from idle, and a bit if you load it on an incline and then WOT (under 2000rpm in my case), but after doing 2 fills under different circumstances, fuel eco was mid 10's then low 11's , so the smoke is not indicative of excess fuel usage, to add to that my EGT has not increased to any noticeable degree.

So if your thinking of doing it contact East Coast Performance Tuning about it, they do exchange units now but they will have yours back within a week anyway.

If you gas it without boost you will blow a bit of soot. Runs clean as once on boost

I fit my remapped ECU today and re-tuned the max boost to 20psi.

If I mash the accelerator from a dead stop I get a very short puff of black smoke until the boost cleans it up. I called Harley @ ECPT with some feed back and he explained it was perfectly normal for an auto DI. There was no observable smoke on light and moderate take offs.

I might try returning my VNT limit screw back to the factory position to see if I can gain more PSI earlier in the rev range. This might reduce the some of the soot experienced during hard acceleration.

I must say, the torque improvement sure put a smile on my face.

Definitely adjust the VNT screw back mate. You won't have limp mode issues and it will drive much better.

For sure - it's on Sundays to-do-list.

Just as a matter of interest, how much did you adjust your VNT down? For sure put it back where it was originally and you will probably get an even bigger surprise with torque.

OK mine a Manual but if I give it a few revs from idle it will pump out a fair bit of black smoke for a few seconds whereas if I raise the revs in one hit from idle I get no smoke, I did a longish video with my camera pointing straight at the exhaust and driving quite a few k's under differing conditions and I found under 2000 and loading it produced black smoke again for a few seconds (still with great torque respnse) but doing the same above 2000 didn't, my fuel eco and EGT have been great so obviously there is nothing to fear there.

I've made 3 incremental adjustments over the years and the screw would be between 1/3 and 1/2 a turn down. I followed your guide and was careful to take note of how much adjustment I've made. Hopefully the paint markings are still on the thread.

I've also noted the EGT readings to be the same as my pre remap temps which I'm pleased about. I haven't done enough km's yet to evaluate my fuel eco - my highway cruise test felt like I was using less pedal input to maintain 100kph. Although my right foot is due for calibration I still consider the data reliable.

I have noted somewhere here that over time I seem to have an average 2% less TPS reading for 100K cruising (cruise control), so yes less throttle for same response seems reasonable with an efficiency increase. I reckon you will pick up a bit more torque when you get back to std VNT setting.

So I returned the VNT screw back to the original position today. It was relatively easy as the factory thread paint was still visible. I was however a little surprised to see the retainer circlip that holds the end of the vac actuator to the VNT lever was missing. I'm usually fairly pedantic about securing fittings and fasteners etc. obviously I just stuffed up last time I was fiddling with it. I'd say it's been missing for quite some time but it certainly hasn't inhibited turbo function. Anyone know what type and size the clip is? I was looking on eBay and the closest I can see would be an E-ring type clip.

Ive noted the sooting issue during aggressive take offs has perhaps marginally decreased although could be exactly the same. No difference in the feel of performance overall although on average, my EGTs appear to be slightly lower than normal. There is more available boost below 2000rpm which is what I was looking for. The amount of 'owling' when I lift off the accelerator has dramatically increased now. Is this ok for turbo longevity? My 100kph cruise boost is sitting between 14 & 16 psi now. I'm heading to Levuka this weekend so I'll see how the fuel Eco goes on the trip.

Cool, I would have expected better response under 2000 as that is why we would adjust it to get a slower spoolup and get rid of limp.

Mine has a very nice whistle around 2-2500, was driving to day with the windows down and it sounded great. I wouldn't worry too much about it, if you were getting surge you would know in other ways. Mine hits 21-22psi under 2000rpm and it loves it.

Don't get me wrong the response is outstanding - I can feel the rear end break traction in the dry on a straight line take off! No way I could do that before the remap. I was just trying to tune out some of the soot but I'm perfectly happy with where it is now.

Hi guys

installed my remapped ECU last weekend. running 20-24 psi. I keep getting a fault code of 46 on the ecu talk. do you know what it is or are you experiencing the same?

I tried looking in the archives but the link to the fault code pages doesn't seem to work for me.

Hi Carl, is that the int air volume error or something?. I'm getting that a lot since the remap. Might have something to do with mafv going through the roof and the Ecu does not know it's not cutting the fuel. ?

I found this description on another page.
Try dropping your boost down a tad and see what happens.

I presume you have removed the DP Chip?

 

[swiftcarl]

yeah dumped the dp chip

will try reducing boost. am also getting a 43 error throttle sensor or something. and an 87 brake something or other lol

I have just fitted mine a few days ago, set the Dawes to 22psi, and went for a spin. Loving the instant torque off the line. I used to have to ride the clutch a bit especially with the aircon on but not anymore. I blew a silicon hose just before and have had to route down the piping a bit. Watching ecutalk I noticed I was having to be harder on the pedal than at 20psi so have dropped to that.

On a side note my ecutalk display dropped the fan on/off line and went to psi, anyone else's do that? I did notice the new ecu is from an 04 and mine was an 02.

I noticed that too, mine is the original 03 ecu, I think it is the icing on the cake!

 

[skegbudley]

I mentioned that you get the boost pressure feature on Ecutalk after the remap a while ago. Bloody good hey.
