steveoexige 65 Posted November 29, 2020 Author Report Share Posted November 29, 2020 This is my 3rd chargecooled tuned Exige and I've always shared the data where possible. Even then they still sometimes end up going bang! Quote Link to post Share on other sites
Popular Post steveoexige 65 Posted November 30, 2020 Author Popular Post Report Share Posted November 30, 2020 (edited) OK, so I had a good chat with the SCS guys and to cut a long story short they said the tune is exactly where they want it to be based on exhaust gas temps, timing, etc. They said they've purposely left the timing on the safe side, just as they won't run any higher boost than the peak 6.5psi I'm currently running. They said that they absolutely wouldn't be running that AFR if it wasn't for the chargecooler and the ECU. They have great faith in their ECU in regards to knock control too, and didn't have much to say about the OEM factory setup and ecu to control knock or fuelling. I haven't collected the car yet but it was interesting to hear them say that they could have tuned it for higher specific power outputs but safety 1st and then the second priority is how it drives, the throttle response, WOT and part throttle, etc. I appreciate your comments about the AFR, but I think those readings in isolation don't tell the whole picture. But "what do they know?" I'm looking forward to driving it bearing in mind its gained 125bhp. Will report back soon. Edited November 30, 2020 by steveoexige 3 Quote Link to post Share on other sites
Kristof Thys 182 Posted December 1, 2020 Report Share Posted December 1, 2020 Will be a blast to drive! And many thanks for the views of SCS/24-7, appreciated. 1 Quote Link to post Share on other sites
Popular Post steveoexige 65 Posted December 1, 2020 Author Popular Post Report Share Posted December 1, 2020 Final update, before I collect the car next week. I spoke to 24-7 and SCS again today and the dyno reading of 0.86 wasn't the final tune. After further tweaks it's running lambda 0.8 which I gather is 11.76 AFR. I've known for ages that the god awful Lotus OEM knock control requires a super rich tune, so with the Delta ECU running the show I'm happy with that fuelling. I absolutely trust these guys, they drive a 600bhp Evora road car also running a charge cooled TVS1900 so they know their stuff. To 24-7 and SCS - I know you will see this post update so thanks for your help and patience dealing with me and all my questions. I can't wait to get the car back. 3 Quote Link to post Share on other sites
