Mapping! A warning to all!

I have been through a few mappers, 3 infact, 1 on the road, 1 on the dyno and the last on a Dynapack!

The last, in my opinion was the best, despite the engine going bang.

This is just to show you, you get what you pay for!

Thats a mess, whats the story?

Detonation, well that was the story!

Regardless of how good the mapper is there is no way they can guarantee the condition of a used car working beyond Toyota's original specs - there is always inherent risk in mapping a car.

Caused by what, something failing or bad mapping?

Bad mapping. There was det in all the cylinders.

True, although detonation is preventable...

Surely any mapper worth his salt would be mapping using det cans electronic or mechanical, so how was the engine detting enough to do that?

only things i can think of apart from bad practice, are injector/fuel pressure failure, bad fuel or over boost.

Screams no det cans or pushing the limits to the extreme

I would be a mixture of gutted and peed off to say the least.

And this mapper was the best of the bunch!

Best let people know so they can avoid.

Indeed. Injectors are new, and were flow tested before they were fitted, fuel pressure was adjusted and evidenced marked and boost was set by the ECU. One of the mappers had used a rediculos amount of timing all over the place, 29 degrees where it needed 17 degrees.

And this mapper was the best of the bunch!

I know what you are saying, however i won't name anyone as i cannot be sure who's map caused it. I just wanted people to chose there mapper carefully.

Surely the last map caused it? If it was one of the previous ones this would have been spotted as soon as the latest map began. 29 degrees of advance has to set off alarm bells?

Should be very easy to distinguish which it was by the period of time in between maps:eyebrows:

My take on it was, the damage was already done, the final mapper spent a good hour or so fixing the old map and got to the point where he was doing the boost stuff, got to 1.3 bar and as he lifted of a puff of smoke and i lost a cylinder. I think the damage was already there and that final boost run pushed it over the edge.

I have my suspicions....

Bingo, that was my point. So the guy who did the most recent work was fixing the errors from the previous map(s).

So it's the previous couple that are in question then?

For the sake of fairness I would, objectively, let the good folks on here know who the mappers were. No conjecture, just fact. You may find corresponding history from other customers.

Ok, i cannot say who caused the damage, all i am stating here is who has mapped the car. I am making NO accusations!

The mappers were:

Martin of MB Automotive (Road mapped)

Austec Racing (Dyno mapped)

I will reiterate, i have no proof and wish to make NO accusations!

Spec of car stayed exactly the same.

Agree with Scott

Plenty of money grabbing cowboys around

Could you at least tell us what ECU you're using?

AEM at the time, both mapped the car on AEM V1.

I would say that's fair enough, who was the 3rd mapper though?

Yes, who was the last mapper or was it Austec twice?

sorry to see this mate , what a mess i cant believe that someone could get the timing so much out 12 degrees is quite abit

ouch!! thats never a good sight
