Suprakeith Posted May 5, 2020 Share Posted May 5, 2020 The spike in timing is controlled via the factory NA ECU. Removing the ACIS setup on the car will not remove the timing spike. It will occur if you have the mechanical ACIS valve or not. If you are using something like an eManage to piggyback the stock ECU, you will need to pull timing out in the ~4500rpm areas to avoid this issue. You will not have to worry about this using TT ECU. I can make a better recommendation though. The "NA-T Bible" thread is really old now, and whilst it has some good knowledge in there, there are a number of areas that I'd recommend not trying. One of which is setting your car up using a TT ECU. Yes it half works, but its more trouble that its worth, trust me, been there got the t-shirt, wouldn't do it again. Rather than spending money on expensive used stock ECU's, then bolting on an emanages and ruining your stock wiring harness to bodge a TT ECU in there. Take £500 go buy yourself an ECUMaster classic & an adapter harness. Now you will have the freedom to do whatever you like on your setup and not constantly have to fight a stock ECU or wonder if its doing the right thing etc etc. Plug it in and voila you have a full running standlaone with sensors for less than a grand. Didn't have that available to us when the "NA-T bible" was written. Also if you aren't looking for mad power, then leave the dizzy in. If you need COP without re-engineering half your engine, leave the dizzy in and use it as your triggering system for ECU. K.I.S.S. Well said perfect idea, when was reading thread did wonder to myself if not chasing big power why mess about with COP and GTE ecu and all the other extra hassle and cost. Keep the dizzy, keep it simple and will make it far easier and better set up aswell Quote Link to comment Share on other sites More sharing options...

Chasz86 Posted May 8, 2020 Author Share Posted May 8, 2020 When replacing fuel injectors on the Na-t can you go too large for bhp or would they just run at a lower volume? Quote Link to comment Share on other sites More sharing options...

I run 650cc Siemens DEKA on an AEM V2 no issue. Previously ran them on a Emanage Ultimate too. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Chasz86 Posted May 8, 2020 Author Share Posted May 8, 2020 I've got an emanage ultimate, and 800cc have popped. I now feel that yeah they way too big, am I right? Quote Link to comment Share on other sites More sharing options...
Josh42 Posted May 8, 2020 Share Posted May 8, 2020 I don’t believe so. 800cc should be usable Quote Link to comment Share on other sites More sharing options...
Chasz86 Posted May 8, 2020 Author Share Posted May 8, 2020 Really OK that gives a much larger selection when trying to pick up parts, I saw a set on the sale pages turns out they are side inlet though a back to being unsuitable. Quote Link to comment Share on other sites More sharing options...
