hi all again
after putting a conrod through my block last week have rebuilt my bottem end know and all is running again
prob is im scard of it it was running lean again as manifold was glowing hot after lest then 5 min of driving however it was not on full boost the dump valve dumps and the turbo chatters but it hesitants when putting me foot down so ichanged my chip and all apears to be ok and pulls fine ithink but my boost gauge says 20+psi whitch is stupied ?my question being how do you tell if thge chip is nackerd and would a boost gayge lie will it be safer to run the standerd ecu till it gose down the garge for a set up and can you put a lap top on there its going thurday so would like info asap pls they guy said drive doen it 5 mls away shall we change the setting on the actator in for less boost as i scard that itl do the same thing???any ideas pls thanks regards barry

 

Firstly what car is it. As a rule no a boost gauge won't lie, but some of the cheap and nasty ones aren't very accurate. Whas the car running at before?

 

the car was rolling roaded and set up before i bought it and after 6-8months i bnought it a striped it down as inside the car w\as missing ie dash etc and ran it in my van but then the bottem end let go,the boost gauge is out my cossie and it works fine then but it like when i hit 3k its bosting 15psi this cant tbe right???

 

Why can't it be right that its boosting at 15psi? I don't think i fullyunderstand what you mean?

 

basicly the neadle gose of the gauge that 30psi and im only looking at 14-15 1bar that with out the chip just on a standerd ecu somthing wrong and when the chip gose in the turbo spinning crazy and the gauge gose off the clock and im not pulling it cutting out ?

 

You still haven't said what car it is

 

sorry it an rst turbo engine s2 that iv put into my m6 van???

 

Well first off the chip shouldn't make any difference to what the car tries to boost at, obviously if it was trying to boost to say 12psi and u took the chip out then it would hit the boost limiter.

Still a bit hard to understand what you have written, are you saying the needle goes off the scale (gauge reads to 30 psi), but you only want to run 14-15 psi really?

 

yes thats what imean
so if id were to drive the car and come on full boost it would be ok untill i hit the limeter right??so its safe or nothave turned the mix screwhalf a turn to rich her up a bit? how and what dose the chip do and what dose it controll??

 

No its not a good idea to run the car if its trying to boost past its limiter (standard ECU is set at 10psi). No i wouldn't turn the mixture screw yourself i'd get it dont as a very minimum on a CO analyser but ideally u want it checked on a rolling road. ERST are infamous for not being able to cope with high end fuelling and its just not worth the risk, especially seeing as you are getting the exhaust manifold glowing. The chip simply unlocks the boost limit, some have a higher limit, some are unlimited.

 

ah ok then ill be getting it on the roller tomoz ill let you know how thing have gone chears for all your help

 

No problem best of luck
