Most of you have seen my shonky old saff a few times and probably accept that, being my own daily runner, it is meticulously maintained and setup at all times, as well as teh fact it does 20Kmiles PA or more pretty much faultlessly...
A couple of nights ago the Dynojet AFR warning light flashed at me when i overtook someone, signalling my AFR had leaned to 12.2 or leaner with more than 22psi.
(The figures i had pre set it to warn me about)
A quick datalogging run was performed yesterday that confirmed the fault did in fact exist and under what conditions:
After some simple checks on fuel system, fuel electrics and ecu i decided it has to be the STD fuel pump starting to struggle with the boost or required flow, so i fitted an 044 last night and did another identical datalogging run to check results.....
Problem Fixed.
The point of this story?
I was sat here this morning thinking about how, as most dead YB owners will tell you, a lean condition never warns you of its prescense and leads to the terminal meltdowns we all know and hate, infact, a well mapped car will normally pick up a few horsepower and feel better than ever, just as its about to let go simply because peak power is nearer to the dangerlevel where it melts than a good mapper will leave it for you in the first place...
Its the slight leanoffs like this that do teh big big damage... not the component failures and other issues like that, its the ones that make her feel that little bit better than normal...
I just thought it worth a mention to remind you all to be carefull out there, even the Pro's can be caught out and if it wasnt for my built in wideband warning system, i could have lost teh my own engine this week, and i do this for a bloody living!!
IF YOU WANT TO HAVE A "HAPPY" NEW YEAR, GET THOSE CARS SETUP AND CHECKED OVER REGULARLY OR FIT SIMILAR EQUIPMENT TO WARN YOU.
