I will say every map I have pulled off of a customers car that was tuned previously by TTP has been horrid... I will agree 100% on Dereks statement. Hell after my 2.4build Derek tried to talk me out of getting the car tuned by him because the MAP I provided would only need minor tweaks... He only had to do minor timing tweaks and adjust the fuel map and was trying to save me $400... I appreciate that to this day...

If that is what the customer requested that is why he did ECU boost... as far a the boost spike, he probably had fuel cut maxed as he was dialing in the boost and intended to set that up after the car was tuned... Tuning for 34 psi and getting a 46 psi spike out of the blue seems like some sort of mechanical issue especially if he was only adjusting WGDC by 4% increments, which in my book would point back to the shop that put the car together... I hate getting handed someone elses work and expecting everything to work as it should...

 

agreed but tough to do in orlando from the choice of shops we had here.

 

Mike,

I know in one of my posts(I didnt go back to look or maybe it was PM to David I said the JE pistons was a mistake I was just stating things as they happened. I did not know what was in the car and was asked so all I had to go off of was your PM to me saying they were JE pistons and my reciept which states JE pistons. I know it was a mistake on your part to say that and not what the 2.4 comes with. And yes you did call me back. Sorry for the confusion.

 

Would a lifted head due to boost spike change the tq readings on the head studs? If they were reading 100ft tq and then showed 80ft tq around the lifted section(cylinder 4) would or could this be a cause of the boost spike? L19 head studs.

 

yes

 

Yeah it can change the TQ spec, when the head lifts it stretches the Studs, so they nuts dont have the same clamping force, which in turn, lowers the TQ they're clamping down at.

It would be more of an aftermath rather than a cause.

 

Thanks for the Input Freddie.. We dont ever suggest ECU controlled boost because its just another electronic variable that can cause problems.. When you add 4% to a map you dont expect 34 to 46psi boost spikes so your monitoring, knock & AFR amongst many other things.. I hate finishing a car that was completely put together somewhere else and everyone always assumes its because we are MAD we didnt do the work.. We are not mad we just KNOW there is going to be an issue as there is 99% of the time.. I cant count on 1 hand the amount of fully built cars that came here assembled by someone else or the owner that didnt have issues on the dyno.. LILLEV was 1 of them & Trents car from Buschur another.. I do recall derek telling me that your map was very good and felt guilty charging you for a tune when he wasnt going to do much to the map.. I have to say it is still VERY SMART on your part to let the shop that assembled the car tune it.. Buschur Built the engine, we assembled the engine and Derek did the initial tune on it which means if you had an issue AWD & BR would stand behind it 100% as we always do..

There are lessons learned in life every day and that goes for us here as well.. Now we will have an Inspection Fee to go over every car not assembled here.. If we find something externally rigged on the car we can only assume there are more things we cannot see that are not done right and we will refuse service.. Its the only way i can see doing things these days with fully built setups assembled elsewhere..

What actualy caused the spike? That seems to be the question not asked and the most important one. If it was a machanical reason than its ttp fault, if it was ecu related its diiirk fault. I dont see how it can be buschurs fault at all...

 

How about if its an electrical malfunction of the solenoid then it might be MAC's Fault right?? I can tell you 100% Diiirk doesnt add 20% or 40% increase to the map.. He makes pulls w/ small % increases.. You can be sure we dont go from 30-40 or 30-46.. He showed the OP in the map the table if i recall and it had a 4% increase.. Electronics fail.. I had my AEM ECU reset on me mid pass down the track 1x and blew the entire engine into pieces.. Do you think AEM would do anything for me?? Nope.. Its all a costly learning experience.. One of which i spent my $$$ on for years to figure out so my customers dont have to.. There is not 1 single car we built here that i suggested ECU boost for or AEM for that matter either.. I have a good handle on what is reliable and what isnt..

Mike

 

No need to get defensive, I was asking a question. If the solenoid is messed up than its a No fault failure. Well its the maker of the solenoid's fault but it was intended for Performance apps in the first place. Its one of those things were a inferior part was used and failed. Theres a lot of coulda/shoulda/wouldas but if Diiirk told him to switch out the part and he didnt it falls back on the OP.

 

Problem with the internet is your just reading the words im typing not my TONE.. Im not being defensive im just bringing up a 3rd variable when you stated its only 2 possibilities and only 2 people to blame..

You are correct these solenoids are not designed for what we are using them for.. When they fail in a situation such as the valve that controls my dyno rollers failed it doesnt blow up the dyno.. the rollers just dont move in an out.. This is why i prefer mechanical devices always because its just 1 less thing to fail.. same reason race cars use mechanical fuel pumps aside from the volume they flow.. They dont rely on electrical components to fail.. the same reason we have never installed a meth kit in 5 years.. its another device that when it fails it can blow the engine.. I went over all of this and educated the OP after the failure happened thru dozens of Pm's.. Unfortunately i couldnt prevent this because the car came in " ready to tune " and we didnt turn a wrench on it.. it rolled onto the dyno and we went into tuning.. Its all very unfortunate but not something anyone can do undo at this point..

Mike

 

He did not tell me to switch this out until after the boost spike when we were trying to figure out what caused the boost spike.

Then Mike explained to me there route with high HP cars and why I will be switching out to a MBC.

 

He should have slowly increased it...

 

How much slower than 2% and 4% additions to the map do you suggest?? The car was on the dyno making pulls in the 20's PSi range long before it ever saw 30..

Not boost. Fuel cut load x2. It's a v7 upgrade. Look at what the load was at the rpm cells. Then input the expected load. That way if the car sees too much load, it cuts full and drops rpm down like the factory fuel cut load. This is one safety parameter. There is also boost error correction table as tscomp mentioned.
