MG ZR: Cams & Maps

[lolsteve]

Right bit of a gutting day then really. 

First off got the exhaust welded up, turns out it had split on the join before the cat at the top so needed the down pipe removing to weld so that was so extra time & $$
Next got it rolled and this is where I'm a bit peeved/confused.

Hadnt seen the equipment before until the car was on and about to roll when I was told "by the way I can't do print outs because the hard drive is broken but I'll get power figures from across the range and write them down to give you an idea"
Damn thats annoying but hey it'll do, more interested in the base peak figure and if the map makes any difference anyway. 

Results of it all was:
remap 123 at the wheels, +3 hp across the rev range
stock 120 at the wheels.

Somewhat disappointing to say the least as this small a difference could be down to other factors

Dug out blueys old rr results to compare. Bluey with a janspeed backbox pulled 115 at the wheels and this current mk2 one has a standard exhaust system and has been sat for 18 months with no history so more hopeful on this engine . 

Also watched the lambda readings for the stock map and at high/peak rpm it reaches about 0.85 or 12.5AFR. Which I think is about right for power/not melting heads

Another note was that the remap file went first and this was very steamy and then very smokey when at high rpm, smokey enough that I had to walk away from it for a bit. Unsure if this to do with the fact its not been revved hard in god knows how long or the cat had gotten a bit funky after all that time with the blow in it. Perhaps the car was running overly rich due to the lambda readings and it finally readjusted for the stock map run. Or i'm just being hopeful that the remap hadn't failed

Oh and after the stock run the car stank of rotten eggs, was quite vile was told it was due to the cat being very hot
