It was certainly metric for mine (mk3)

Yeah if it did it with the engine running and then was fine immediately after with the engine off - it would point to clutch/slave IME. However as you describe, more likely linkage related.

When it next does it, switch the engine off and then try - should rule out if its clutch/slave cylinder related. The usual problem with these boxes (aside from s**t synchros!) is physically not being able to select gears when cold - usually fine once warm so yours is the opposite you are...

Ha no worries I'm becoming a cam shaft nerd right now as I'm deciding what to use next :) When do you think you'll have it mapped on the rollers etc to get a bhp figure? Have you had head work?

Sweet car but are you sure those are 433 cams because you have a dephaser still on the inlet and 433 are VVT delete. Do you mean 423 perhaps? Anyway, got any power figs? :)

Cool, hopefully the cams are ground better and more consistently than Cat's hence v.tempted by them right now. Should go nicely in a spare big valve head and then just call it f'ing quits frankly! yeah I've seen the Access has a tool like the grp N in the parts catalogue, but the 2 Maxi R3's...

nay mind, I wasn't holding my breath ;) Look forward to when you can finally crank this beast over though. I may have asked already and probably forgotten, but when you built the engine did you dial gauge the timing to check or just rely on the horseshoe? Reason I'm swaying towards R3 cams now...

Any updates over the festive break? :) Sorely tempted to bung some R3 230 cams in mine so I'm extra eager now to see what yours makes and the shape of the curve etc ;)

Cool, cheers dude

ah cool - I'll set mine as you've done then at 16psi low warning and see how it goes! what sample rate you using? 0.4 as it is out the box I presume on all? cheers

I installed my SPA dial the other day too, what have people set the high resolution sample rate to? I've left mine on the what I assume is default which was 0.4. But it can go from 0.1 to 25 in .1 increments. Also I've only driven mine cold a couple of times since fitting it (max oil temp so...

Yeah I understand that mate, but it's one of those common things I see in print on forums all the time and it doesn't stand up. Paul will (should) know, so I would infer he was talking about cam timing - but that's why I wanted to point out it's not a mapping thing on an NA car, as it's a...

I don't get why I read this so often on a simple NA engine, UNLESS, you are takling about cam timing? (though most people are not). If the cam timing is staying the same..., then the ignition advance and fueling maps at the top end do not have an optimium that is mutually exlusive from an...

I bought some (Arrow) about this time last year from Marks contact - best price I could find by some margin.

Yeah possibly, although it turns out SC actually themselves do a Bosch 4.9 wideband with a controller in the wiring, and then it can easily pin to 4 pins out from there. Though they seem to think a narrowband will do the trick anyway so will wait and see!

It's an SC (Delta 800), been built for p'n'p application by SC themselves so hence using the OEM loom and 4 pin cabling for lambda that's there as standard. Yep that's why I am running open loop now (ignoring the fact current sensor is also not giving a stable signal anyway) as I don't want...

Good point, so I've asked and they've advised wideband straight to the ECU, not to worry about a controller and gauge etc - but, my wiring on the car (standard Renault loom) is for a 4 pin lambda only - and a wideband Bosch 4.9 LSU sensor is 6 pin. Not sure if I can re-pin a sensor or not? So...

Hi, I've got a standalone and it's running open loop the whole time. Apparently my lambda sensor wasn't giving a stable signal and the thoughts were it's screwed. Not sure if I should replace it with an OEM narrowband or get an after market wideband kit? I suppose with the wideband I then have...

Well it's speculation on my part based on a few "facts", the only person who I found 'using' 403's and said they needed pistons - turned out to be using 404's lmao!!

I think you can run 403's on standard pistons without cutouts, and this is an opinion formed for a few reasons. Firstly the considerable gain in lift going up to a 404, it's bar far the biggest jump between any 2 profiles on the exh cam. Second the 403 has less peak lift than even the 402, so it...

Bloody OEM ECU's, the more I know the less I know it seems. Moral of the story, standalone and ITB's! Cheers

Just curious but how come the duty cycles are different above 4500 if it's open loop? I would have thought once open it'll use the pre-defined values in the map so would be the same for all 3? - The difference in airflow then being directly referenceable by AFR? I must be missing something...

Cool, nah it's a top effort with all you can use at your disposal. So the line like / is the duty cycle? the line like \_ is the AFR yep? and the flat -- line is the ign?

These flat out runs then with the ECU in open loop? out of interest when does the Clio drop closed loop, certain throttle % and/or rpm's?

You're possibly as lazy as me! Yep it's an SC using DBW TB, wasn't a case of just bashing the Meg one in as needed new can work and harness apparently - still not sure if it's running as yet, wasn't when I spoke on Monday still needed the VVT stuff doing. The plan was to pick up on Friday so...

Looking good mate, you could have this running by the weekend ;) and mapped the week after!! I want to see what these damn R3 cams are like!!! Should get mine back this week with a standalone now, will make for a better comparison and I can judge what cams to use next!!

Yep, have them now in front of me, they have the same part number as Meg 225's on the body of them... 8200511099! They have the same 8 hole design pattern as the normal Mk3 injectors too, so probably why they have a good rep for atomisation etc. They did cost me £186 delivered instead of £132...

I was reading an article by David Vizard the other day and there was a section about using bigger valves to address the common issue with modern 'sporty' 4V heads having excesivley large port sizes, which our heads seem to be a victim of. Short verison of it was to cut in big valves properly and...

197 head onto 1x2 block from the other week: http://www.cliosport.net/threads/197-head-and-internals-in-a-172.782219/

ha no worries, threads served it's purpose as 240bhp on 422's is not as wild as I thought. Honestly thought you'd struggle to get there on 423's in all honesty. I think I've established 230bhp would be the sort of minimum figure you want to hit on 422's, any less and you've got a probably...
