Twingo Adey's Twingo GT (F4R+T 2.0ltr engine swap)

Good luck with the sale mate, its turned out pretty epic. I was hoping you would keep it a bit longer so i can have a go in it😁Agreed a lot of pleasure building stuff like this and getting over the i
Cheers man, I'm still mulling it over lol 🤦‍♂️ , I've had the advert written a while now. If I sell it I will miss it but the funds would go towards more tinkering, though I will still be carrying on tinkering with this whilst its here. Its just so easy to use and drive now, even quickly and I still have more things id like to do to it. FFS I'm talking myself out of it again 😂 if its still around at a track day you are more than welcome to take it for a blast (y) as you know 270/280bhp per tonne isn't a shy vehicle. Would be good to do some pulls against both of yours (y)

I was running the car up on the drive and noticed the rad fan wasn't cutting in... checked the dash and we were at 103 degrees. Quick check showed the resistor pack had failed again.... very strange. Fan is totally free to spin so hopefully just an age thing. From what I understand is it runs the fan at 2 speeds but with it bypassed it will just run flat out. Quickly tested and it worked fine so I gutted the resistor and bridged the connectors so it's all still oem looking.

Turns out my fan wiring issue maybe a little deeper routed, another thread posted up for that as I could do with some input. My good neighbour lent me some real sweet diagnostic kit as i have a few little issue with the Twingo. An abs fault was my first to look into, after clearing all the legacy items I was able to see the current issues. DF026 front R/H wheel speed sensor. the live readout also shows its doing 655kph so hopefully it just needs a new sensor. I was able to correctly code out the front airbags, one from the dash that's been missing for years and the one for the Meg 2 steering wheel (wooo that lights now off)

Whilst I had the kit I was playing with the actuation of the fan and found it would pop the fuse when requesting the high speed fan, also causing the stop sign to illuminate and warning beep to go off, I have the same thing happen when I start the car and intermittently when I use my over boost switch which is a completely independent system making me think I have an earth fault on the high speed side of the fan wiring. The light that comes up is actually there for the brake fluid level as far as I can tell.

Great bit of kit to use though, wireless and easy. With a price tag of 2k plus I'm told, it should be! Also spotted a stored code for going too fast 😂 from the spec it looks like it will ping it for going faster than 134mph...

I woke at around 6.30 this morning with a thought that I may have wired something backwards. If the resistor and fan were plugged in the wrong way round it would be easy to check with the wiring diagram and wirings colours labelled......


Yep id plugged the fan wiring to the resistor pack, and the resistor pack wiring to the fan 🤦‍♂️

Anyway after diagnosing that I swapped them to find the fan was now running backwards, that was a super easy fix though, just de pin and re pin the connector and the fan was back to running the correct way. Funny how it ran in the correct orientation with the incorrect wiring lol. Checked with the diag kit on both both low and high speed request (all one speed as I have bypassed the resistor) with no more blown fuses (y)

One more fault to fix with the abs sensor, which I'm assuming is all that is required but I will investigate and make sure this afternoon. Thanks for reading 😁

So final for this weekend I think. Abs sensors checked, I get a reading off the known good one but nothing at all from the dodgy one confirming I need a new sensor, so will get that ordered up 👍🏻

I also got hold of a dash switch, whipped from a laguna at the scrap yard. It's now wired in on my boost switch setup for permanent full power. Sounds a little silly but gives me a few options of how to drive the car/deliver the power. I now have low boost as a default (circa 190/200bhp at a guess) overboost/overtake on a switch on the steering wheel, giving momentary full power and then the full power all the time via the dash switch 👍🏻

It looks like I may of had another fault but not really realised. Recently I've kind of thought the car, though still fast was a little flat. I put it down to the ambient temps being higher and just generally getting used to the power as you do. Yesterday whilst doing a pull it hesitated then carried on. I didn't think much of it as it was so brief but enough to feel. This morning whilst on the way to work it went flat when just driving normally, like a car running out of fuel (my fuel gauge isn't the best so could of ran low 😂 but it wasn't) I then watched the lambda correction on the dash all the way home, noting that it was constantly trying to add fuel and when pressing on a little it would feel flat whilst trying to add huge percentages of it in.

Anyway I whipped it out this eve and slapped in a spare Nissan R35 GTR pump. Initial test would make it look like the pump was dying off or not able to keep flow as I've suddenly gained a chuck of power, smoother power and an eagerness to rev. Scared me again lol. Will see how it behaves and feels over the next few days.

I didn't really get any pics as I was covered in petrol (y)
