MGRover Remaps

[Bogbrush82]

I'd be down for one of these, But I've got to replace the diagnostic socket on my car first. Somebody had damaged the pins before I bought it so it's not talking to anything right now.

This maybe totally irrelevant.If a custom map is carried out to the vehicle.How is the vehicle category defined for insurance purposes .Do you have to show the insurance company dyno results? Also are the standard braking systems ,transmissions,engine mountings etc etc adequate for the maps .Please dont take this in any way as negativity but we all know how insurance companies twist and turn to avoid liability.I fully understand the way engine characteristics can change with mapping as I personally map engines on a daily basis .These are gas engines with outputs of between 200kw to 1500 kw.

I have a bit of a background tuning Honda's on S300 and Crome (nothing fancy i am by no means an expert)
So could you give me the run down of what could be done on a 190?

The reason i ask is because the engine is coming out for a rebuild in a few weeks, and while its out speaking to the engine builder (AMAC engineering in Northallerton used to build my dads Mk2 escort rally motors etc)
He said we can easily add in some headwork to open it up a bit for very little extra cost.
I've also read a lot of posts about running an intake cam on the exhaust side or exhaust on the intake cant remember which one, but basically i would love to have a more useable higher rpm and better mid range
The inlet manifold is gutted and de-flapped so could you incorporate that into the map?
I also have a stock fully working inlet if you wanna run a comparison and finally put that myth to bed?

Thanks!

Head porting on N/a enignes is a tricky thing to get right and can very easily make things worse. There's a lot of fine tuning in the factory to maximise volumetric efficiency through inlet pulse timing/exhaust scavenging and a bad porting job can really mess this up. Do they have a flow bench at all ?

Exhaust cam on the inlet I think is the proposed idea, never seen it done or heard much about it in practise. Think the cost of messing with the Kv6 puts alot of folks off.

I'd be very interested in testing the de-flapped vs working manifolds. Think I know which will perform best but the results would be the true teller.

When I'm finishing up with the ECU side I'll drop folks a message and to check the very generous offer still stands

All the best with this venture.

Thank you

That's a shame to hear, guessing some one rammed in some diagnostics equipment. Are the pins ruined or just pushed back?

Good point. When I've declared remaps to insurance companies previously there's never been a question of custom or not. Generally they ask is it over X value HP if they even ask at all. As such if it's declared they shouldn't have any come back.
Brakes are a tricky one, you should always have sufficient braking to suit the car but.... 30mph is 30mph regardless of how much power under the bonnet so a simple town driver wouldn't necessarily require an upgrade. If you're ramming it down country lanes then it might be worth looking into just in case things get a bit too toasty...
Those are some impressive figures, is the mapping for efficiency purposes/design of new models/maintaince

Pushed in I think. Tried to get it to talk to a T4 but the results were all over the shop.

The engines I work on are powered by methane This is created by anaerobic digestion .The methane content is not ambient and can range from 52% up to 90% The rest being Hydrogen Sulphide .Thus the requirement for constant mapping .The requirements are stability to attain a constant running speed of 1500 rpm this enables the engine to produce power at 50Hz enabling the set to synchronize with the grid .Obviously power output is important So the maximum output is required without losing stability . As you are aware there are lots of factors to be taken into consideration when mapping engines other than maximum output .One advantage with petrol engines is that the octane ratings are pretty stable and turbos are quite inexpensive .The turbo temperatures on gas engines can rise in seconds from 700deg c to 1200deg c due to a pocket of gas being released into the manifold .Replacement turbos when this occurs cost in the region of £35,000!

Yes, the perfect remap is the one that the customer is 100% happy with, and one that will not cause any damage to an engine.

Ah so it's a biogas engine? I've heard of a few power stations popping up that run on Bio fuels, the name Drax seems to ring a bell.
Those are some toasty temperatures, might seem a silly question but are like similar wastegate/VNT units or are they perhaps oversized so as to avoid the need for these mechanisms? Still...wouldn't want to be the guy to explain to the boss that the turbo just blew up haha

Indeed, spend an evening out hunting for the biggest fireworks I can find and find things diverged a bit.
In terms of dates, looking at either... 19th November or 10th/17th December. If no good then happy to postpone to the new years?

You don't have to have an OBD socket to get a remap. The 160 map via postal service is written directly to the ECU. I'm sure other tuners offer similar.

An alternative (although not necessarily a great one).

[CivilSteve]

This is true, we can write files to it without the car/obd socket.

However for dyno tuning (which is recommended for best results) we would use the OBD for data logging purposes as well plus if making multiple adjustments it adds a quite a bit of time to the process to keep disconnecting/reconnecting etc

Out of interest, what sort of returns could be expected from a remapped standard 75 1.8T auto tuned for extra economy and torque rather than all-out power?
