So are saying no no to red dot now? I've always heard good reviews but I must admit this has put me in a predicament for my project now
But happy days you got yours sorted buddy!
Try speaking with James at turbo dynamics I've received got great service when I recently got my turbo rebuilt for my accord type R turbo
I will answer this in the most diplomatic way I can...
was the Autolusso Map I drove away with better than the red dot one..? yes undoubtedly...hands down.
however none of the maps tried changed the point of boost, what I had was a car that was un-driveable at various points, let me explain.
1st gear needed lots of right foot to get moving but the second you changed into 2nd boost was lost so drop in power foot down to keep momentum, then into 3rd..assuming you are cruising at 30 mph in town in 3rd at 1800-2k I had NO boost so putting your foot down resulted in nothing for a good 3 seconds and then a belch of smoke and a push in the back at around 2300 rpm
smoke implies fueling was fine, we had mused that the smaller injectors in the 150 engine ''might'' be the issue also we mused it ''might be the fuel pump as again its different from the 170 pump, lower pressure.
combustion is simple, two components, fuel and air, so physics 101 if the car is boosting late this is down to the calibration of the VNT mechanism IF all other possibilities have been ruled out.
they were. the car had a new MAP and MAF when the turbo was changed and a new VNT solenoid and new vac hose and boost hoses are autolusso silicone ones...and my car unlike Damien's has no FMIC so less volume in the intake should result in less lag not more.
ALL the Autolusso maps were an improvement on the red dot one but none really changed the shape of the torque curve, peak power was increased for sure and maybe altering the boost levels bought it in MINIMALLY earlier..say 100 rpm. but the acid test for me was cruising down the road at 30 in 3rd and hoofing it..still nothing for a good long while and then some power.
on the motorway 6th gear was unusable as I would be doing 90 (theoretically officer) to have the turbo on any kind of usable boost...where I would normally select 5th,4th was better,where 4th 3rd and so on but you cant drive around town in second so that is the situation in which it was most annoying..and not what I paid good money for.
so.. Ned offered the other hybrid as a solution, I was very confident that my turbo was not right so elected to do it. now bear in mind if it was the same I would have to accept it was my car or car/turbo combination added to which although Ned looked after me yesterday he is not a charity and rightly so, I was taking a gamble financially. and when else would I get the chance of a direct comparison..?no brainer really.
anyway,after it was fitted I got back in the car and went for the acid test 30mph in 3rd and bingo! car on boost and she goes off like a kicked cat with the normal very minimal lag....on the A of bang. which is normal for these cars, on the way home every gear is usable at the place you want it, 60mph in 6th is on boost enough to respond when you want,basically the power band crosses gears and it didn't before.
4th and 5th are animal! but she is better all over....honestly grinning like the village idiot on the drive home..
bottom line, we did and could have continued throwing maps at that first hybrid all week long..it just wasn't right...the second it was changed the late boost problem cleared up so QED it WAS undoubtedly the turbo at fault.
so in conclusion,does the TD hybrid work on the 150 cars..yes absolutely ,you don't need the 170 pump or injectors to do it, my car goes as well as Damien's now and there is some more there if I want to tap into it at a later date, although the 170's will make more power when pushed, I think Damien's set up will get him 260+ and I think he will squeeze 280-290 out, where as the 150 cars will be limited by injection at around 230.
stock cooler is good enough at stage 2. (IMO) but we will evaluate that in the summer.
worryingly there is a marked difference between the two hybrid turbo's mine and the replacement..now given they are both 777250-1 to begin with and re-worked to identical spec they should be the same, given the whole premise of turbo dynamics operation is consistent precision engineering then the two turbo's should be identical.
they were not, for me that is a ? that is yet to be resolved, I will hold back judgment until TD have the original back for inspection.
what made this whole thing solvable was the intervention of Ned. so I would advise anyone buying a hybrid and doing the mapping for a GT/147/156 go through Ned, he knows what they should do and in the event there is an issue, if the map,turbo and installation is all done in ONE place you will have a much easier time of it in the event the car does not meet expectations.
this has been a rough,frustrating and costly time.
had I have elected to have it all done under one roof problem solving would have been easier,quicker and cheaper and TBH if Ned went back to turbo dynamics saying it wasn't right I suspect it would have been acknowledged immediately and sorted. I questioned the turbo straight away and as told by Turbo Dynmics ''it is likely something else'' and to be fair to them in these cases it normally is..
so to answer your question, I would go to Ned for mapping over red dot ..I don't want to get caught up in anything political but the AL map is the better of the two...even before the turbo swap, red dot do not specialize in just Alfa's Ned does, it isn't just the map to consider but also a working knowledge of the mechanical's and where it can be pushed and when to hold back.
no offence to red dot and Paulo did point straight at the turbo when the car was not right...but I can only speak as I find and am just relaying my experience to the forum.
if you plan a hybrid on an Alfa then def Ned all the way IMO
in retrospect having driven been in Damien's car and wanting to emulate it ,my decision to go to red dot seems a bit counter productive.
to quote Ned ''every day is a school day''
you live and learn.
