Could someone explain when a long rod piston reaches tdc the dwell is longer and may cause det:handsup:

The 2.0 LR set up is a well trodden set up.
Indeed you get more dwell at TDC but that certainly wouldn't cause Det.
If you are posting this from a therory point of view then as long as the build is sound, everything machined and measured correctly, you should not see Det purly through a rod ratio change.

Arron what are the reasons given for you're car suffering det ?? Theres plenty of cars in the north that run super unleaded without the problems your having my car included. When it was still going that is lol

When it was built I run it in on std injectors which where cleaned first as I thought that why the piston failed. So new turbo put on and ecu and ID1000 and road mapped on superunleaded with octaine boost as when coming onto boost det was heard though ear cans but not via engine light as the simtec ecu warns u by. So though that the compression ratio was wrong as in to high. Talked with Gav at Rosssport and the static compression ratio is 8.8:1 so run it on race fuel and no det. I think that Steve Simpson didn't spend enough time on setting up and have wet det but afr sensor up the exaust says all is good. So when boost comes in ecu brings in high relay which ups fuel to 72 psi from 43 psi so maybe std fuel reg not up to it. It costs £300 to bring him over so asking questions before I bring him over next month. Don't get me wrong the car is a flyer at the moment. Mat I think his name is at the TRL said Steve knows what he is doing.:wallbang::mad:

The problem you have is you have chosen a ecu that has little support so you cant change the mapper easily so you are kind of stuck.

Arron get your hands on a motec. Dave rowe comes over to Strabane every few months. Maps a few Evo's and skylines. The map won't be the issue after its done.

Fuel Regulator

Should ID1000 injectors fuel ok on std regulator or go for aftermarket adjustable FPR:smthumbup What would be the benefits :smthumbup

Yes new build but what I cant understand is. On std injectors no det on ID1000 det with ear cans. Now a 255 lph pump when switches over to boost maybe over powering FPR, but lamda sensor up the exaust was giving good numbers as in no rice det. It looks to me the mapper is not up to it. I know the fuel is not great overhere as Dermot says there is are loads running around with no problems. One point I would bring up is 3 subarus have have piston problems to be sorted out at the garage who looks after my car. I think det is more prevalent that people think.

Correct me if I'm wrong. But the octane of the fuel allows more timing to be run? So if you are using lower octane fuel the timing has to be adjusted to suit? Detting can happen on any octane rating? So to me it's the mapper?

Yes I agree. As the simtec ecu has very little support, this means I will have to change ecu £££:wallbang:

Well as the saying goes "choose your mapper, not ECU"

Sorry mate these things never stop costing :(

Do you think there's any damage from the DET?

Have a second opinion on your map from a different specialist.

HAve you pulled the plugs and looked at them properly?
