Excellent work! Great write up. One suggestion - I'd be tempted to take the power for the wideband from the ECU 12v feed, splicing into the loom just before the ecu plug for more accurate and reliable operation. You know I have had second thoughts about the cig lighter too, just seems like an easy choice rather than the best one. I am seeing a very small variation in wideband gauge display to AFR reading in TS, I mean it's not miles out at all, but there is a slight difference there. Yeah, you'll get a much better signal straight from a clean 12V line. I took mine from the radio harness and it never worked right. |

Yeah, you'll get a much better signal straight from a clean 12V line. I took mine from the radio harness and it never worked right. Well my thinking was that if I remove the cig lighter and run the 12v to the wideband, it's basically got that line to itself? I'm really not electronically minded so that thought was probably wrong. So I've got two alternatives now, tap into ECU 12v, or tap into the main ignition switched 12v as per Car Passion Channel's wideband install video. Not sure which is best really? |

Yeah I'm not sure how the sensors and stuff differ in a 1.8, but if it's a case of just adapting the loom plugs then go for it. Though I suppose there's probably more to it than that! I'm in the same boat, I considered another ECU, but the price would have meant waiting a couple more months at least to get it, and also not a fan of the attitude of a particular creator involved, seems a bellend. Not naming any names, but yeah...
A quick Google suggests it may be a bit painful, no sign of anyone who has done an adapter themselves but there is mention of swapping pins so it must be doable and it's the sort of logic I can work with
Always good to have plenty of options. A couple of years ago there was the "megaspaff" ecu on eBay which was a rip off MS so it's good to see something at a lower price point that is more legit
Yeah will be a pretty involved project if it is in fact doable I'm sure. Please tell me it was actually marketed as "Megaspaff"  if it was I'm almost not annoyed at them for making a crappy counterfeit ECU haha. Yeah it's great to see it developing, and being written and the code released publicly as Atlex said. |

So I did a few more hours of driving today, and further improvements have been made. In terms of Acceleration Enrichment I have reduced the Accel Time field from 700ms to 300ms currently. This has almost eradicated the hesitation issue I mentioned yesterday. Kind of a rotary/2 stroke sound to the exhaust for a split second, then carries on up the rev range quite well. The issue before I made this change can be seen here: Notice the slight hesitation as I hit 2nd, then the more pronounced hesitation as I hit 3rd. Almost gone now, but still happens a tiny bit. Current Acceleration Enrichment settings (graph values are basemap figures, I have made no changes):  Accel enrichment settings 28-05-18 by Chris Oldham, on Flickr You'll also notice I've now activated Deceleration Fuel Cut. I brimmed the tank, did 79.7kms, then brimmed again. Not really long enough I know, only put in 8.78 litres, so works out at 25mpg after conversion. Not bad considering it runs rich and I have done numerous 0- 80 err 60 pulls  . However I thought I'd give the Decel Fuel Cut a go. Using the basemap settings, I just changed the TPS Threshold from 1% to 5% just in case the TPS signal was noisy. I am having issues though, it's a bit jarring coming back on throttle lightly during cruise, and can be very jerky in traffic when you're stop start constantly. Anyone with experience see anything amiss? My initial impression was to put the TPS Threshold back to 1%, I will check my most recent datalog I made today but I don't think my TPS signal is noisy at all. Perhaps I don't even need this setting to be on? I also mentioned last night that I had concerns about heatsoak due to my temporary K&N cone filter setup. Well I ran a datalog yesterday evening, it was still pretty warm out so that will play a part, but I was seeing intake temps between 32 ā and 55 ā, so a little higher than I'd hope for really. Fitting an enclosed intake and re-attaching my Randall Cowl routing should see these drop though, I will update on my findings after I have fitted it. It would be rude not to show off the Launch Control after telling you that it works, so I made a video of it. Here are the settings:  Launch control - Flame mode by Chris Oldham, on Flickr Yes it's a low rpm, and yes the timing is very retarded (much like myself), but this isn't a feature I will be using, I just fancied a quick brap for the camera, and it is now deactivated in my map. Sorry for the sound quality, I filmed it with my proper camera and video is not it's strong suit, the mic is really crap: It did a flame. It made me jump and I laughed like a child. Won't be using those settings if I ever decided to use it, will likely blow the welds on my intake (dangertomanifold.jpg) /s Back to work tomorrow but will keep on doing bits and pieces when I can. Still need to secure the ECU into the car, tuck the wiring, and re-fit the ECU cover and carpets. Plenty of little jobs but I'm happy to say it has been a great success so far. |

As long as it shares the same 12V as the ECU, you should be okay.

Flames = awesome lol Can't go wrong with a bit of flame. I mean apart from eventually destroying the backbox baffles, probably the 02 sensor, and all the gaskets in the exhaust system haha. |

I retarted the ignition on zero throttle for my ITBs, which basically meant every time you lifted off, flames would come out the back. The baffles lasted about a week  |

Saying that did it do anything to your wideband 02 sensor? I imagine as they run at such a high temperature anyway the odd bit of flame wouldn't hurt them. |

I ran a LC-1 for 5 or so years like that and it still read the same as the day I installed it. |

Well that's good to know, I've seen a few bad reviews about Innovate widebands, but I'm always a bit skeptical about what I read online. |

So I decided to lower my TPS Threshold percentage in the Deceleration Fuel Cutoff menu as I mentioned before, as my TPS signal appears to be noise free 5% may have been a little high. Big thanks to Martin Y on Nutz for his thoughts on this as well, made me more confident in my plan to put it back to the 1% threshold that the original basemap had when it was deactivated. Also raised the Cutoff RPM from 1,500 to 1,800. It now transitions so much smoother than before, so much so that I forgot it was even active after a while, no more jerkiness at all during cruise or in traffic. Here are the current settings:  Decel Fuel Cut Off settings - 29-05-2018 by Chris Oldham, on Flickr Also couldn't resist having another play with Launch Control huehuehue. Set timing to 0 degress during Soft cutoff from previous -4, and raised soft cut off to 2,750rpm from 2,500rpm. Decided to get some footage in the garage. DO NOT RECOMMEND. My ears are still not feeling right haha, massive flame and bang. Got a great still from the video though:  Speeduino Launch Control. Big flames by Chris Oldham, on Flickr |

Great write up, I'm somewhat tempted to give speeduino a go if they develop a pnp 1.8 one... Hey Guys... Don't want to hijack Bilbo's thread, but I thought I'd jump in briefly. I'm the developer of Speeduino and just finished off the initial designs for both the 64-pin NA8 and NB8a boards today. They still require testing (I need to find some cars to test on!) but these are definitely in the works  Josh |
