why are power fc ign values different to ecuflash ign values. this there a formula to work one to another.

iam looking at lots of ign maps cos i got my car from my tuner and it has max knock of 20-30 and wont to take abit of the timing.

272 cams evo 7 21psi

payed $1000 with 2 visits

should i be happy??

 

You paid $1000 for tuning and your getting 20-30 counts of knock.

You want to know if you should be happy???

May not be the tuners fault but he should have been able to give you some insight as to what may be wrong with the car, not just take your money and give your car back f'ed up.

 

Installed Arp headstuds on my car 1000km ago. no water loss 20psi + do I need to retirement them. Thanks

 

A) Go speak with the tuner and try and sort out what is going on. If you paid $1g they should get you exactly where you should be w/ no more $$$

B) Headsuts normally need to be rechecked/verified with another tightening sequence because of joint creep of the aluminum head and headgasket. Some creep more than others so some are going to tell you "no you dont got to do that ****" and others will tell you "yes you should do it"...... keep in mind only because you don't have an issue doesn't mean they don't need to be retorqued. For example if the tightening torque is 80ft-lbs... the joint creep may loosen the clamp load something equiv. to 70ft-lbs, this type of condition is why they are retorqued.

 

thank you. i did retorqued. thank you for taking your time to write
