Kpcseven Posted June 8, 2019 Share Posted June 8, 2019 I know the real answer is to put it on a dyno but I’d like to avoid the expense of that and even if I do the closer I start to correct the less time and money it will be. I have a Vauxhall with Swindon 218 hp option setup with Webers and the ecu was replaced before I got it with an Electromotive XDi wasted spark system. Seems to run pretty well but I wondering about optimizing the advance curve as the curve now is just the suggested curve for a 4 cyl engine from Electromotive. . Does anyone happen to have an advance curve for this engine or some guide on how much advance to run?Long shot question I know but I thought I would try. Thanks.

Kpcseven Posted June 10, 2019 Author Share Posted June 10, 2019 A bump here just in case anyone with a Vauxhall has any information. I did inquire Caterham as well as Swindon and no information available. Link to comment Share on other sites More sharing options...
Tazio Posted June 10, 2019 Share Posted June 10, 2019 Send a message to ECR, he knows his XE engines.. Link to comment Share on other sites More sharing options...
alan c Posted June 10, 2019 Share Posted June 10, 2019 I cannot provide a map or any advice on the correct advance to use but I went exactly the same route with a VX with the same Swindon set up a few years ago.I purchased a second hand ECU that already had a map on it that was good enough to get me to Northampton Motorsport. The map felt good but after a couple of hours with Troy it was much better. All of this is a long winded way of saying I don’t think you can avoid a mapping sessionIf you do this be prepared the 218bhp claimed by CC was optimistic - mine does now achieve 218 but it is now on throttle bodies and the engine has been rebuilt with lighter flywheel, modified head and a few other improvements.

ECR Posted June 10, 2019 Share Posted June 10, 2019 The info that I have is on the 250hp JPE tune so not relevant here..... A mapping session is the answer I'm afraid and I agree with Alan, the CC claimed power will be optimistic .... Link to comment Share on other sites More sharing options...

Kpcseven Posted June 13, 2019 Author Share Posted June 13, 2019 I have searched but not found anything. Searching the Low Flying archives is not easy. Link to comment Share on other sites More sharing options...
alan c Posted June 13, 2019 Share Posted June 13, 2019 I do not recall seeing anything about this and I have had my VX for 10+ yearsThere were three different “Swindon” options and I think only about 50 sold in total so number of cars with same Cam as you have is very limited.So it is a long shot to find what you want. Northampton Motorsport mapped mine at similar stage to you and again after rebuild so they do “know” the engine Link to comment Share on other sites More sharing options...
Kpcseven Posted June 14, 2019 Author Share Posted June 14, 2019 Alan, Thanks for the information. I didn’t know that there were so few Swindon engines sold. I’m located in the US so your engine builder suggestion, while appreciated, would be a bit far! The Vauxhall was engine wasn’t sold in anything in the US so it’s a fair bet to say that nobody near me is going to be familiar with the engine!thanks,Ken Link to comment Share on other sites More sharing options...
