Weathers bad today so doesn't look like I'll get a chance to look. Just did I little 2nd gear WOT with no hands. Car pulled to the left by half a lane. Also tried to pull back right about a 1/4 of a lane. When driving the steering feels less weight turn left. Turning right feels fine.

Ok the steering on my 182 doesn't feel right. It seems very keen to change direction when going over bump, white lines etc. also when pressing on you have to fight to keep the wheel straight. At the same time the steering feels floaty. Sorry only way I can describe it. I checked the steering...

Joins the 2 together. No flange.

Replace the cat to center section mount. I'd also replace the center exhaust mount/hanger. Only use Reno parts.

Looking at some ignition logs, the 9x20 looked to match up (warm 98 Ron). The 16x16 maps don't match up.

ok think I've found the load axis some googling has come up with the factor and offset. Will up date the doc later in the week.

Thanks scoff. I only have a generic obd scanner for logging so not very good. I was thinking of getting a Reno clip but it's been mentioned that rstuner is better at logging.

Thanks. Will update the doc.

I've put a document together of what I've found so far. Hope it help users and hope users can add to it. http://www.hidden-power.co.uk/wp-content/uploads/2012/08/Siemens-Sirius-32-34-Guide.pdf

Well moves standard except for a janspeed cat back. So std renault part should be fine.

Thanks Paul. Your help is appreciated. I'm trying to put a document together that compares the maps between a 182, 172 and the group n file I found on the net.

It was genuine. Thanks will keep this in mind.

All sorted now :)

Yes. You have to cut it to replace either the center section or the back box.

Manifold, cat and the cat back is a one piece system standard. 2 piece if you go after market or requires replacement.

Ok found the 16x16 spark maps. Are we saying these are spark limiter map? Or the actual spark maps? If the actual ones then what are the 9x20 ones earlier in the file? Looking at a group n file the earlier maps are altered I think from memory. Not found the 16x16 maps in that file yet.

I used a viscous spanner. Was fairly straight forward. Hardest part for me was getting the rubber boots back on.

Thanks. Confirms which what I have found.

That from a full read ? Think I have a full read 172 somewhere.

That's interesting.

Will try and send some later this week.

Thanks for the info. So does rstuner log things like knocking, injector duty cycle?

I've only got the partial 32kb read. That was using a galletto clone. Not used the mpps clone yet. Yes forgot to add the offset which I have as the same as you. For the ignition maps I've found the size are 9x20 in 8bit. Yes I gave the cam shifting map. As it's not 20 in size, do you know...

Will do mate. Another trip to my friendly dealer. Need to pickup the air filter anyway. Thanks

So bit of searching and it appears these are cups that fit in the flange. Mine looked buggered lol .

Left work this evening only to find the exhaust blowing :( On inspection the cat fitting bracket has come away. Now looking at the manifold the nut and bolt hole is not a complete circle. Is this as per design or has it rotted? Pictures to show what I mean.

Mine use to be bad for a couple of minutes then like a switch would be fine. I've since replaced the exhaust and it's fine now. Original exhaust had loads of holes in it.

Yeah when you use ECM titanium, the map definitions are not the greatest. Best using different mapping software and find the maps yourself.

I have the following from my 182 Sirius 34 ECU. 01455 Ignition Cold 98. Factor 0.375000 01509 Ignition Warm 98 015BD Ignition Cold 95 01671 Ignition Warm 95 01916 Fuel WOT Cold 98 019CA Fuel WOT Warm 98 01A7E Fuel WOT Cold 95 01B32 Fuel WOT Warm 95 028E3 Fuel Part Throttle 03C13 VVT Cam shift...

I use winols as I've never managed to get my head around tunerpro but then I never really tried. I've found some maps but not sure where the load axis is located in the maps. Also what the factors and offsets are. My understanding of the Sirius is as follows. Cold and warm timing maps for...
