Tom Tucker Donating Members 614 Member For: 4y 9m 20d Posted 03/05/22 10:18 AM Author Share Posted 03/05/22 10:18 AM Breakfast laps at QR sucked. The track was wet, so I had zero traction. A few people crashed, so I'm lucky I avoided that. And nothing broke, which is handy. Just refining the tune. Having issues with it leaning out between gear changes, so I get hesitation. I'm assuming decel settings need to be investigated. Anyone do momentary ignition cut on gear changes, clutch switch activated? Link to comment Share on other sites More sharing options...

You been asking keef for boost control tips?! Decel is literally deceleration which is when you take your foot off the throttle and let it coast in gear. It has nothing to do with a gear shift. A lean hesitation after or while reapplying the throttle, is likely caused by not enough throttle pump enrichment or not a quick enough return to open loop fuel control. Farken people jump the gun and rather than sort the map out properly with no corrections, they try and tune with every farken correction enabled and as such end up with a car that runs like a bag of dicks. I've spent a long time just sitting in my driveway stabbing the throttle to get various cars acceleration enrichment sorted, after the base maps are done. It's a pita but it needs to be done for a complete tune. 1 Link to comment Share on other sites More sharing options...

He was half mile racing or something at a airport. Don't ever think he found a clutch that could truly handle it. What bov you got?Alternatively nitrous seams to work for this fg Link to comment Share on other sites More sharing options...

Sounds spot on Puff. Stabbing the throttle on idle results in coughing and spluttering with AFRs bouncing around from 10 to 22 Link to comment Share on other sites More sharing options...

I want to do flat shifting in mine, but it's a long way off being tuned... Though that video above of NOS in between shifts sounds interesting.

Tom Tucker Donating Members 614 Member For: 4y 9m 20d Posted 28/06/22 05:04 AM Author Share Posted 28/06/22 05:04 AM Bit of an update. Had the tune revisited, and it turns out the changeover from NSP to NEXUS software screwed with correction tables. I also changed out the Dyno-Mite stage 1 cams for Atomic stage 3. Huge thanks to @JETURBO for hooking me up. The Atomics are actually more responsive, make more midrange by about 30kw, 100Nm more torque and also make more peak power, up to 613kw. That reminds me, this thread needs a bump up... 1 1 Link to comment Share on other sites More sharing options...

How good would it be to test every camshaft back to back with the 2 most common upgraded turbo sizes, 35r and 42r?! Link to comment Share on other sites More sharing options...
Tom Tucker Donating Members 614 Member For: 4y 9m 20d Posted 28/06/22 08:55 AM Author Share Posted 28/06/22 08:55 AM Yeah true. So reviewing the data in more detail, there is up to 45kw difference in the low to mid range. Pretty amazing. The strange thing is the Dyno-Mite cams might actually be slightly faster in reality because of limited traction Link to comment Share on other sites More sharing options...
