Stonkin Posted December 29, 2008 Share Posted December 29, 2008 (edited) Was mapping tonight with Ryan and Charlie at SRR. After a couple of AFR issues lately and with Charlie (B'Have) not ever getting the car on the rollers after his many years of ownership and hard work that he put into the car it was time to check it out and see what was going on. The car is a T61 auto and made [email protected] fly and around 475/480 lbs torque if im reading the graph correct? The autobox was a concern and over this was starting to slip. Ryan also mentioned the wastegate spring needing replacing for more but is not worth it unlesss changing the box. I'm sure Ryan will explain better. All in all was a great evening, thanks to Charlie and Ryan who has been a great help with getting it sorted Was nice to meet Wez and couple of other guys (i am crap with names ) thanks for standing around in the cold to watch and advise Have thawed out now Here is the graphs, only photos as i have not got a scanner handy Edited December 29, 2008 by Stonkin (see edit history) Link to comment Share on other sites More sharing options...
Dash Rendar Posted December 29, 2008 Share Posted December 29, 2008 Awesome. So that was at 1.35 bar? The AFRs do look a bit odd. I would have expected it to be a lot leaner before the boost comes on, and without that 'dip' in the early spool. On the other hand... I don't really know what I'm talking about!! (But I have had a lot of AFR issues in the past, so I'm endeavouring to draw from experience.) Edit: Oops, you already said, 1.4 bar. Link to comment Share on other sites More sharing options...
Ryan.G Posted December 29, 2008 Share Posted December 29, 2008 Thanks for the kind words chap Was an interesting night trying to get the AFR's perfect like you can with a standalones but that change over point on the stock ecu where it cuts the fuel is a PITA to get out with the EMU. Normally load cell holding allows me to get it but with the way your turbo spooled it was difficult to say the least! On Lui's car i could get rid of it but yours was not having it, even though the Injector duty out on the logs was smooth and the fact it didn't effect the curve at all. On the road you never see it as the kick down puts the rpm in the areas past the Seq change point. Ryan Link to comment Share on other sites More sharing options...

Ryan.G Posted December 29, 2008 Share Posted December 29, 2008 "but with the way your turbo spooled it was difficult to say the least!" What was strange about it Ryan? In english please It spooled so damn fast it was hard to load cell hold the engine at the point as any slight movement on the pedal and it was then 1.3bar Link to comment Share on other sites More sharing options...

b_have Posted December 29, 2008 Share Posted December 29, 2008 Nice torque curve, 500 horses should be easy at 1.6. My first box held up at 1.6bar for around 5 years although it was never dragged. Link to comment Share on other sites More sharing options...
Stonkin Posted December 29, 2008 Author Share Posted December 29, 2008 Definetly think there is more in the engine Charlie, but it is driving great One day hopefully it will be a manual but for now can concentrate on other parts of the car Link to comment Share on other sites More sharing options...

Stonkin Posted December 29, 2008 Author Share Posted December 29, 2008 Why is the torque figure higer than the bhp? Charlie? Link to comment Share on other sites More sharing options...
b_have Posted December 29, 2008 Share Posted December 29, 2008 Why is the torque figure higer than the bhp? Charlie? Don't know, but that area under the curve is driveability Link to comment Share on other sites More sharing options...
Wez Posted December 30, 2008 Share Posted December 30, 2008 Small turbo and small cams = great road car Nice to meet you this evening, took the whole journey home to get the feeling back in my toes Link to comment Share on other sites More sharing options...
Ian C Posted December 30, 2008 Share Posted December 30, 2008 I saw that AFR curve and thought "I bet that's an E-manage" haha Once the weather picks up I'm going to have to pay SRR a visit with Mr G and a fitted water injection rig See what we can see...

Stonkin Posted January 4, 2009 Author Share Posted January 4, 2009 funny Will sort some new pics out soon At the moment i'll be leaving the autobox, and look to a 6sp conversion at some point. The autobox is still great and if used properly can be very rewarding, and also relaxing when you want Link to comment Share on other sites More sharing options...
