I'm pretty sure the map on the Emanage is supposed to be a base map to allow you to drive the car to the mapper.

 

 

I think its meant to be more than that and that it just/perhaps needs a dyno session to optimise things.....what stops the boost rising on this kit a weak wastegate spring?

I also think it's more than just a map to get you to the tuners but the boost is limited just by the wastegate spring which should be set at 7 psi. The statement in the Whifbitz blurb looks like a standard caveat which they would be foolish to leave out.

 

Question is "what boost pressure is it achieving at cut-out?". If it's more than 5 or 6 psi then maybe there's something wrong with the wastegate pipework or the spings in the wastegate need checking (AFAIK there should be only one).

indeed and fwiw I don't think the guy is having ANY sort of pop but if he has been working all day (no idea!) and then got to fire it up and do a shake down test drive and it's boost cutting why not start a thread on here....but yes I'd advise a call to Whifbitz tomorrow too.

I would only ever check an engine will fire up and run for a few minutes at fast idle, to check for leaks, before having a car on a dyno with a competent mapper present. I am not a believer in maps for X spec engines, driving "base map" cars ANYWHERE at all, and certainly not in attempting to create boost on a new build that isn't on a dyno with all the necessary readings being watched by a competent mapper. I am amazed how blase people are about running a new build without it being on a dyno with the mapper watching everything like a hawk. I have seen some real disasters by people "just driving it to the dyno", or "round the block".

Have you checked the map clamp voltages? If they are t set the ecu will see boost which it doesn't like,

Secondly where is you map sensor tied into, is it t'd into the stock map sensor?

What boost are you seeing at cut?

The statement reads that they have a generic map on their emanage, but I would want it on a rolling road to check.

Right after a bit more work it turned out to be the wastegate. It was taken off, dismantled, cleaned and rebuilt and now the boost is correct. As for the fueling issues the emanage does not have a map installed so i will hopefully get the map downloaded onto the emanage tomorrow and let you lot know how it drives. Out of curiousity has anyone else on here using the full whifbits turbo kit?

I will be using the majority of the kit, but not the SMIC, I have a standalone ECU and I'm running 650cc injectors

I'm using the full kit with some extra additions such as low compression engine, EManage Ultimate, 650cc injectors, ACIS delete, air con delete, flexi fitted to downpipe, single O2 sensor conversion etc. :)

Scary stuff. Brave man to consider doing anything other than tick-over to see if it runs when you know the eManage is not mapped to do the fueling.

 

I will be using the full kit on stock compression. Additional parts to begin with will just be Wideband, Boost Controller and BOV.
