Discussion
I have a base 110 running a map.
On a track day last year, the engine was reluctant to rev much beyond 5000rpm - with the power fluctuating on wide open throttle.
The dealership had a look and said they thought it was running rich but not much else.
It's had the fuel pump replaced.
I was on track today, and got the spanner symbol and check injection warnings, and it went into limp mode.
It's booked in again next week, but any ideas?

Postulations from my own experiences with other cars;
May be worth inspecting the spark plugs as a quick and easy insight, especially for an engine that spends lots of time at high RPM the usual intervals are quite long.
Running rich, pulling power and general power loss, particularly with a remap and on track makes me wonder if it was part of a protection strategy to reduce exhaust gas temperatures / more generally manage engine heat - It isn't uncommon for the engine to begin managing output (i.e. Cutting power) before onboard coolant gauges move past the "Normal"
Do you have any logging from the car at the time?

There's a chap called Neil who posts here, but I dont know how to tag, had a similar issue, and KTec have been working on it, and was something to do with the new fuel pump and updated OE software and the aftermarket map...
Interesting. Mine started misbehaving before the replacement fuel pump. I thought the issues were due to it starting to fail - obviously not!Haltamer said:

That's a good shout re plugs - someone also suggested that at the track yesterday.May be worth inspecting the spark plugs as a quick and easy insight, especially for an engine that spends lots of time at high RPM the usual intervals are quite long.

Conditions were cold and wet yesterday - it wasn't a great day to push the car. We had an OBD reader - nothing flagged, but reading other forums, it seems that not all faults are logged.

I had the same issue with my car on track also. When running in sport or track after 15 mins it would go into limp mode with either and emission system or injector fault message.
Fortunately i could clear the codes with my OBD reader and running the car in normal mode with no issues. I'm convinced that the pops and bangs in sport and track are the issue with unburnt fuel going into the exhaust on over run. I wonder if its an oxygen sensor or cat issue.
Did take it to the dealer, but no codes stored as I'd cleared them on the track day. Will see if the problem comes back when on track next.

Just adding my experience - in gears 1 to 6, the engine in my PE with Life110 map (I have no reason to suspect there are any issues with the map), will rev to the red line; in 7th it will flatten at 5,500 rpm, which is about 140mph, leaving me with quite a few metres to the end of the Kemmel straight at Spa where it’s just cruising. Has anyone seen the red line in 7th?

Sorry to hear you woes spoiling your track day, with me it was more than one track day, as you can imagine not without considerable expense.
IT WAS THE MAP despite denials from the tuner. Assistance from a top mechanic help me eliminate all other possibilities.
My car now runs perfectly, thanks to Lichfield tuning.

Is this the emission system warning light? We couldn't work it out, and Google image search wasn't conclusive!Fortunately i could clear the codes with my OBD reader and running the car in normal mode with no issues.

Neil, are you on Litchfield's 305bhp/415Nm map now?
And from your post history, you were previously on a Life110 map?
Yes I did have the original TRS Life map on my P.E. and it worked well purchased 4/12/2019 for days after collecting the car. And from your post history, you were previously on a Life110 map?
Not sure what the figures are for the Lichfield map but combined with their gearbox upgrade the cars performance is better than it has ever been.

5500 RPM in 7th should be equal to 149 or 150 mph, depending on the tire size, what is 5 mph close to the speed restriction of an A110 without aero pack. 6200 RPM in 7th would be equal to 168 or 170 mph. Is the max speed restriction deleted with the map you have?Edited by James Elmer on Tuesday 28th January 20:42

I'm still at the top end of 6th there :-(. I must need bigger balls!Edited by James Elmer on Tuesday 28th January 20:42
