Seicento Monster Cento/ECU Master Thread

[blu73]

it would be so awesome to have an appropriate box connected to the seiT, its such a shame the 500abarth one doesn't just bolt on I never knew it was the same as a PGT box though, they can be got for not alot of dollar these days - it beyond my knowledge though as to how i would go about either making it fit or perhaps somehow making the internals fit inside a box that would fit. But it has always annoyed me the ratios being just a bit silly on the oem box for a turbo cento.

Well, I'm hoping to control the torque/boost spike using the mappable closed loop boost control which is a rather nice feature of the DET. And if the clutch does slip I will obviously upgrade the flywheel/clutch, however I'm not overly concerned it will be an issue. As for a change of gearbox if I was going through the efforts of modifying something extensively to fit, I can assure you it wouldn't be off a Fiat. As much as I love most things about Fiats the chocolate gearboxes and notchy gear change isn't one of them.

Are you seriously selling your house just to make Fiats and buy a Ducati Fingers? Seems a bit excessive.

Nice pile of bits, nearly as big as mine

Bit confused about the positive camber bolts?
Why do you want positive camber? I'm in the process of making adjustable top mounts, I don't like the idea of the bolts

 

[Honeymonster]

Never heard of one breaking however I will give them a go and see if any improvements can be made to the handling.

I meant negative of course or adjustable, well spotted.

If I had the time and fabricating skills my car would look more like Teodor Kocurs, but unfortunately I don't.

However Brooky I beleive you do, at least the skills anyway.

Something to consider for me down the line soooooo much to do already!

Well, the council want to buy it under what used to be the pathfinder scheme to knock it down. So, I have to sell and I can get a nice housing association flat as it's classed as a compulsory purchase.

So, at 60, and realising you can't take it with you, why not! :yum:

 

[Honeymonster]

Can't say I would do any different if I was put in the same situation. Although it is a shame about your house of course.

Am running thoe camber bolts in a few auto-test now. It seems fine, but one down side is everytime you take the struct off you need to have it retracked..

This is possible the only project that starts with everything you need!! I am constantly buying bits, but the way you are doing it looks so much more fun, just fit fit fit fit, test, fit fit fit fit

Enjoying the building process, once it finished you be missing it

Tiny update as I haven't been able to get to the car today. I cut out a plate to fit over the old rev counter hole out of aluminum with a nibbler. Then covered it in some 3d fake carbon to match the standard Sei Abarth interior. It's a bit of a beast but it contains 6 gauges. The leds at the top show battery condition and charge, then we have RPM, boost, oil pressure, oil temperature and water temperature. It also has a huge shift light I won't be using however I will connect the output to something much smaller and more practical. I also couldn't resist the urge to take it apart and check the build quality and was suitably impressed.
Twin stepper motors, trims for calibration, quality SMD and through hole components all mounted to a nice round triple custom board. It cost £60, insane!

Hopefully I'll have time to fit it tomorrow. It will be a lot tidier than my cinq which had gauges everywhere that's for sure. Sei really isn't suited to pods either. Now I just need to find a home for the EGT, knock and WB gauges.

 

[blu73]

Looks like an awesome bit of kit!! expensive??

 

[Honeymonster]

Nope not at all for what you get chap, much vheaper than buying individual gauges, however if money was no object and centos were OBD2 I'd would of bought a GTECH EGS for sure:



You can implement wide band and all sorts of other features on these bad boys, then there's the PLX DM6



:worship:

Very cool toy, if only it would also show EGT

Yeah I know but at least it got the majority of the important ones out the way without chopping up the dash.

The EGT I got is 60mm too no idea where I'm going to put it yet. Knockgauge is small and easy to hide though. It retrospect I would of bought a knocklite for the output.

However I'd already bought one of these in kit form:

I don't regret it though it was fun to make.

 

[Honeymonster]

Fitted the gauge without the extra senders atm, so only rev counter, battery charge and backlighting working (no point fitting senders until I fit the other engine).



Looks pretty good fairly pleased even if it is a bit on the big side, might paint the outside matt black. Evening goes on, helping my mate change a clutch on a new Punto for the next few hours, eat a take away then a bit of friendly banter...

It's 1am, got in the car to drive home. Ahhhh my eyes!! Good grief it's bright, looks like a christmas tree through the hubble telescope.



Next job fit a dimmer circuit to the backlight before I go blind!

Hopefully suspension and powdercoated bits will be fitted this weekend.

 

[Honeymonster]

It's 3pm on Saturday aftermoon...









It's 6am Sunday morning and I can hear the seagulls squaking outside, its gone light, dark, light...



That was rather a long evening.

Nice rear shocks I took off the cinq are fubared and were leaking in the box, will have to get some new ones and stick with the standard ones for a week. Other than that and having to retap every single powder coated thread it couldn't have gone better. No rust under the car at all so that's a result. Only got the rear end done, will do the front next week. It sits -40mm back standard front ATM lol. Also drank rather a lot of red bull and don't feel to great today. :spin:

A rather legendary famous grafiti chap has managed to find me a 75 TB too. :slayer:

You certainly don't hang around loving this already and will be keeping a close watch

Thank you, thank you.. I'm here all week

That is a beat of a gauge I like very interesting thread would love to see how the ECU management comes out I know you said it's a brand new GT17 turbo but what is it off as I think they use different models of the same turbo housings ect...

 

[Honeymonster]

Hey Brin

As you say there are many variations available in a Turbo of the same series. I have spent quite some time trying to work it out but it seems when it comes to turbine sizing the proof is in the pudding. Smaller turbines spool quicker but cause more restriction and vice versa.

Since the GT17 I have (GT1749S) is off a diesel it has quite a large turbine/housing but not a huge compressor/housing (common for diesels).

Working out compressor sizes however is much easier and of course the compressor size is bigger than that of an average GT15 so one one would hope for more power. However many people have run hybrids or 17's with much larger compressors/trim.

Anyway this particular GT17 is off a Hyundai 2.5 litre diesel H100/200 van.
It was aquired for a measly £150 which is of course crazy cheap for a brand new turbo.

I'm hoping int will do me proud however I couldn't recommend it to anyone until I have tried it. On paper my calculations always seem to come out on the low side and I'm still happy with the results so I guess we will just have to wait and see.

Blu is an absolute Legend!! :worship:



Just needs a quick clean with some wheel acid.

Manifold is ready



injectors are ready



Fuel rail is.. er, well needs some work. Maybe I should send it to Punto Project for a good polishing. LOL

New bearings have been fitted to the powder coated hubs and the fun starts again on Saturday. Going with the GT brakes however the calipers need shotblasting and powder coating. Jimbo (the powder coater) is on holiday for 2 weeks so the brakes will probably have to wait until he gets back.

Still haven't decided on replacement suspension, will probably go with uprated Kybs and get the FK springs coated black so everything looks standard (on the outside).

i can do this lol
