Re: zs 180 remap resualts

Looks like that has a vis issue as well !


The torque graph has more hills than the Himilayas !

The zs had std 177ftlb torque !

Pointless having a remap when there are vis issues present.

I would have done a health check on the rollers first and then gone from there.

We used to see the odd one or 2 zs`s achieve 200bhp with our stage one remap. Wirlys was one of them.

So 200bhp isnt exactly breaking news !

Re: zs 180 remap resualts

had vis motor tested a week ago at an mg garage all are working fine but i know it faster and run better than ever so F**K it plus you wasnt there george and your just ****ed of cos i warned not to buy the super charger off you and you lossed a sale of £1350 and every other remap the guy had done had same sort of torque cruves

Mate ive been doing the zs v6 a long time now long before reidy remaps came on the scene, so dont tell me how to suck eggs !

Your car has a vis issue full stop and just coz it went to a rover garage means naff all matey.

I used to have MG sending quite a few mgs to me to check as dealers couldnt find the issues with them by using t4.

T4 cant always diagnose correctly and thats where a rolling road comes into play.

Dave v6 has even commented on your graph, the proof that there is an issue is plain as day in that graph.

If you also look at your before and after graphs, the issue has moved further up the scale because of the remap.

Dave and I have done more to a zs than anyone else on these forums and we both know bulls4it when we see it.

I dont give a to55 that you didnt buy the charger mate, it can wait for the next car i have planned for it.

If you do a search on vis, you will see my posts date well back to 2003, as I was the one who discovered the vis issue in the first place and made it known to the general public.

So find the rock you was under please until you have substantial knowledge about these cars and there idiosyncracies to put me to shame with, then i perhaps may listen.

Below is a graph of a healthy zs 180 showing no dips or steps in the curve

Scaling is still done in 500 rpm increments.

The switchover is supposed to be a smooth one, and shouldnt show as a door step on a graph. It should stay a smooth progressive line.

You shouldnt have any large dips in it.

If the vis system is working correctly, then the crossover shouldnt really show !

Drew why is it you can never post without having a stupid dig? Do you own and operate your own rollers????

Stop your silly digs and if you are going to post on the subject then at least give helpful advice to the guy who has the issue.

Roverdave, the problem maybe vis related but it could be that the slider mechanism in your inlet manifold is worn/stiff which is causing the change in transition to be slow which is causing the dip in your graph.

Re: zs 180 remap resualts

no silly digs in this thread...

the plot you posted, saying how wonderful it is, actually has some large dips if it were scalled properly. which considering you have a rollers should have been obvious.

the helpful post is dont listen you someone who thinks they know everything when they clearly dont.

try taking a proper look at roverdaves graph, the 'slow' transition your pointing at takes 200rpm and covers 5lb/ft. the first dip in your amazing plot is over 10lb/ft and takes 500 rpm.

well done, your completely wrong again.

Drew

No you are but i will leave it up for others to decide.

There isnt one zs 180 that has been through my workshop with running issues thats not left us corrected !

So i am happy to say yes i do know it all when it comes to the vis issues with these cars, but thanks for pointing it out again.

Cheers

Mgdavid.

I would say you do have a small issue around 5k.

It seems to drop away a bit quick and then pick up again, by which time its run out of revs.

I reckon your zed should easily make the 175-180 mark if you ironed out that drop.

All the ones ive done have never ended up with them dropping off in power after 5k.

Vis motors who would have them eh?

Talking cars, it wasnt my graph, it was one from the G force rolling road day back in 2004

A few zs`s then had issues, which was when i divulged the vis issues.

sorry, my misunderstanding

No worries.
