As you may have seen, I fitted a new exhaust and de-cat last weekend, then set the ecu free to do it's stuff.
It's taken less than a week and it has completely re-mapped the fueling, it was a bit rough at first, but now it's pulling cleanly, and strongly, up to 8500rpm. ( average increase across the map is about %8 )
I am just sooooo impressed with this bit of kit!!! |

Just be carefull when rapid tuning, i think its blown my turbo apart. I rapid tuned while racing down to London early one morning and was getting some serious backfiring. I didn't help the matter admitedly as once i realised i could do it i was spiting flames for about five mins now ive exhaust gas finding its way out of the turbine housing
Removing it later to see the extent to of damage. |

Sorry to hear that Kei. I hope that damage is not too severe.

LoL, not sure I'd have been able to resist that either But on a more serious note I hope it's something simple like a blown gasket.
I was running it in 'slow converge' with the timing set to 'closed loop' to avoid something like that happening. Not sure the 'rapid learning' is designed to be used for more than a quick initial setup to give the ecu something to work from |

Kei> you were in "rapid learning" mode ?
fxdlidon> timing in closed loop means using the knock sensor you fitted to prevent knocking, right ? And slow converge on fuel loop means using the embedded O2 sensor in order to tune the fuel map to reach the target AFR, true ?
And another question, but unrelated: how does the ECU control boost pressure ? The wastegate isn't mechanical ?

Yes i was in rapid learning mode, which i suspect as Don say's should really only be used to get a basic timing when first setting up.
Rapid learning and slow converge for fueling both use the stock O2 sensor to reach perfect AFR.
The Ecu can control some aftermarket electronic boost valves, i just use a manual valve and my boost gauge.
I hope it is something as simple as a gasket, i'll have the manifold off too so i can give it a good check for cracks.
And boy did it spit flame the passenger mirror gave a good view of the orange bursts. |

The standard ecu setup doesn't control boost pressure. It has the facility to do it, using an electrically operated bleed valve in the wastegate actuator pipe, but none of us have tried this yet.
This was going to be the next thing on my list but given the increase in performance from the new exhaust (and a couple of "incidents" this week) I think better brakes and more rubber on the road need to be sorted out first!

Clever, I am feeling clever at present after fitting an Adaptronic to the son's car the LGD. (Thanks for the plug Don) Also went the hole hog and fitted a new analogue TPS, 3 bar MAP sensor and knock sensor. Had a heap of problems at first with dodgy sensor readings but finally nailed it when I worked out the alternator on the car was shagged.
Stupid me took about a week to work it out as if I dont know enough about an adaptronic by now but thaks to the F2 screen and a couple of logs it soon became clear. Electrical interference caused by the alternator caused havoc with some of the sensor readings in particular the water temp sensor which is right above it on the engine.
As you have probaly read in the tech section I have sorted the alternator and loaded/tested a couple of ecu files I have saved from KOF33 and all is great! Cant get the son out of the car now. |
