it would be nice to see AFR and timing in these plots...
Lee, thanks for the PM tell me you made your own pipe.Hi Lee,
sorry to hear you are having difficulty.
PM me your number and i'll call you. Providing I made it and you aren't happy, i'll give full refund and replacement pipe in the post next day. We've received nothing but praise for this so far, as a result I'm pretty confident it's an installation issue.
Stupid question, but check that the gasket between front turbo and the modified pipe is properly in place, i've seen them hanging out before now!
ah dammit. That was my gut feeling. Time to break out the laptop and spend the night road mapping.If the car is coming up sooner, might be in a different box in the map. If you are 2-3-4 degrees off, it might feel slower. You will often feel this as it will feel better at low throttle as you normally get more timing, have more timing in those areas of the map.
Well see how it goes and report. The cars I tired it on, only one was back to back with no tuning. The others were new builds and tunes.But anyways, thanks for confirming what was ligering in the back of my mind. It does feel like timing is about 4 degrees retarded when spooling up. Just that little bit of sluggishness.
Just to keep people updated........Lee, thanks for the PM tell me you made your own pipe.
The shape of the dividing plate makes a big difference, took me 4 iterations to get it how i wanted it!
Good. I was the one that started this thread, and I liked the mod. It made sense to me, and hearing it made it much worse for someone really makes me wonder.Just to keep people updated........
Lee has fixed his issue, turns out he had a gasket problem.
He's a happy man now though!
What was your 60 foot on the 12.45 run ? [email protected] isn't bad though honestly.A thousand apologies to the guys that have not yet done the pipe mod, that might have been put off by me reporting boost probs since fitting the modified pipe. so bloody laggy ! Still, 12.45 @ 110 is not slow for a stocker... 12.20 next time:thumbsup: Lee.
So what you are saying, is that I was correct. You guys shouldn't smoke weed and drive. ha ha ha.remapped ignition. Added 2-3 degrees timing in key places in the first quadrant, lag is gone, and the car spools faster than ever.just require extra mapping to make maximum use of the pipe mod. boost is smoother and builds much faster, the boost needle moves noticeably more quickly around the dial than before.
How "perfect " is your 20 degrees BTDC ? If your gun is off, your mark is off. In a perfect world, should be dead on. In real life might be off 2,3,5 degrees. Better to notice what your car likes and wants than the straight numbers.I've got a max of 38 degrees timing advance in the 1st quadrant of the map. Seems like a lot, but the car seems to like it. A lot. Any eyebrows raising here at that much advance at 2500rpm? (I revised ignition from 2500 to 4100rpm, load up to 12)
