Ess ts2 tune

Hi everyone, So I've got an ess ts2+ on my manual 330. I'm also running Schrick 272/256 cams. Everything runs fine. I'm just curious as to what my options are for an aftermarket tune whether I should go reflash or piggyback or standalone engine management. I'm in Melbourne Australia, so if anyone has any recommended tuners, that would be great.

With the bigger intake cam possibly effecting engine vacuum, are you getting boost at the correct times/ reaching full boost? Would an adjustable bypass valve possibly be an option to adjust for any lack of vacuum?

Nope, on an NA engine you get no bang for the bucks. Best you really can hope for is pushing the revlimiter up, who also is the worst you can hope for.

Davcon have you been able to find anyone in Melbourne that can tune your car using the standard ECU? I had my OEM ECU custom tuned here in Sydney and have not had any problems...my ESS tune was not good at all and I was down approx 20+kw. After retune car is running great and it has survived 6 day long track events revving to 7K RPM.

Haven't had any luck finding a tuner in Melbourne. Ideally I'd like to retune the standard ecu. Who in Sydney tuned yours? Perhaps they have contacts in Melbourne

with SC isn't it better to have more lift on exhaust?

All the supercharger specific cams are more duration on the exhaust ( that I know of), davcon is in the predicament that he put these cams in prior to deciding on FI, and can't find data on the performance of these cams with FI, and the ess standard ts2+ tune. They work, but are they optimal?

Would consensus be, power wise, for replacing the 272 with a 248 intake cam, tune the ecu for the 272 cam, larger exhaust cam, or will there be too little difference to bother?

Davcon my car was tuned by Dave at Silverwater Auto Services - http://www.silverwaterauto.com.au. I believe he does alot of the custom tuning for active BMW club/race cars here in Sydney - Peak RPM etc. Unsure if he does work down in Melbourne so you will need to contact SAS to find out more.

As to your 272 cam question, as much as I'd like to take a calculated guess at this I'm not. I think your very best answer is sitting at Silverwater Auto. Once there tuner takes a solid look at your motor & setup, he'll be able to determine if you should swap out the 272 cam & replace it with a 248 cam, based on his years of expertise.

If you Really want that "tune" down in Melbourne, start preparing yourself for the 8.5 hour drive. It will be worth it in the end.

Would be interesting to put it on a dyno before you do anything more. At least that way you will have something to make some sort of comparison.

I'll organize a dyno run next week... And depending on what the outcome is, a road trip may be in order

Ess ts2 tune

I think personally, that you should plan your end goal. How much power are you hunting at what revs. How much are you willing to spend?

With NA, the cams you have peak outside of your current rev range, I believe from other posts, peak hp is between 7100-7500rpm. Combine this with FI, and I think realistically, the dyno will tell an interesting story here.

My engine is supposed to cut out at 6800rpm, but for some reason it hits the 7200rpm mark before cutting out on the dyno, the 248/256 cams still seem to be climbing.

Unless you are planning to rev over 7200rpm, and up to 7500, I honestly think change the intake cam. If you want to rev inside this range, change the exhaust cam (big money on head and bottom end).

If you plan on going stage 3 ess, leave it as is, do the cam when you machine the head/ do the bottom end.

If you plan on strengthening the bottom end with stock compression, and want to play with boost levels, custom tune will be needed again, and another trip to Sydney.

As Rob43 has pointed out, speak with the tuner, he will know best, but you need an end plan now you are running FI and still wanting more power.

hasn't Adam been clear in his experience that the M52 and M54 engines cannot go much higher than 7200

I was under the impression it was 6800rpm, as per spec on there website for ts2, but have also just noticed there is no rpm listed for ts2+. That would explain why it revs to 7200 rpm lol
