Nodalmighty Posted July 1, 2007 Share Posted July 1, 2007 I would imagine the block can be sleeved to recover the bores (typically £100 a hole). We do it all the time to 3S-GTE blocks when customers have had 87mm overbores that have gone pear shaped. It's a shame you have had a bad expirence with the mapping side of things as it's going to make the next time even more of a Mapping should be part of the tuning experience, I always involve my customers in the process as much as possible as I always find they relax more when you talk to them and let them know what you are doing and why. Both the dyno's I use (Race Shack's 2000bhp Mustang & PJ's 1600bhp Dynapack) will allow the customer to be involved. Making someone sit and wait in a room while you give their car 6 and out in a dyno cell is a bit rubbish. Even if the dyno I was using had a no customer policy, you would still get a turn as I do 80% of the map on the road. I only use the dyno for refining top end where silly speeds on the road would be just too dangrous / costly and to obtain a figure for Pub Trumps Lyndon.

Alex Posted July 1, 2007 Share Posted July 1, 2007 I think I should add a disclaimer to my spark plugs post.... Don't use IRIDIUM'S when MAPPING! Reason being, the iridiums don't break...sounds odd but they are so immune to det that other bits suffer first....like pistons. Do use Iridiums once the car is setup. Copper plugs like NGK BKR7E's will fall apart when det occurs, stopping the engine firing....this is handy when the mapper hasn't got his detcans on and has missed the fact det is occuring!!

Sorry Alex but that is the complete apposite to every experience i have/and a lot of other people who have run them and had det! Every time i have seen an iridium plug that has disintegrated/melted it has been due to det! and Denso in particular! I always use std type or platinum for this reason. as they fall apart and cause more damage. Anyway on to plugs in the pics, if these are iridiums, then i have to say that the det was only for a very short period of time as otherwise as i said they would have been destroyed, this is why i asked to see them.

Steve Posted July 1, 2007 Share Posted July 1, 2007 Not trying to shit stir or anything, but it would have been nice for Dan to comment on this as he was viewing it a little earlier today. Quote Link to comment Share on other sites More sharing options...
Supra ST Myster Posted July 1, 2007 Share Posted July 1, 2007 just curious, did you still have to pay Dan for the mapping session? Quote Link to comment Share on other sites More sharing options...

Supra ST Myster Posted July 1, 2007 Share Posted July 1, 2007 Yep I have to pay for the mapping session hmm Bit bad really, damages your engine and then you have to pay for the pleasure of it also! Quote Link to comment Share on other sites More sharing options...

Steve Posted July 1, 2007 Share Posted July 1, 2007 Exactly! In fact, Dan should be paying out the money to get this fixed. Quote Link to comment Share on other sites More sharing options...

Steve Posted July 1, 2007 Share Posted July 1, 2007 The pistons were in mint condition when you had the head off. Now they are fooked due to det whilst being mapped. How is that not his fault? Quote Link to comment Share on other sites More sharing options...

How is that not his fault? As he said in his reply to the thread he blames the engine and perhaps fueling, he has told me himself that he is not responsible for the damage, 'these things just happen sometimes' Honestly I dont see him coming forward and doing anything about this, and I did not expect that anyway, I just wanted to highlight the dangers of mapping and ensuring you get the car mapped exactly they way you want it and get advice on what the limitations are and should be, although a mapper should be giving you that advise IMO Quote Link to comment Share on other sites More sharing options...
Steve Posted July 1, 2007 Share Posted July 1, 2007 He didnt map it to how you wanted though. You wanted 1.5bar, he then tried to map it up to 1.75bar. I know we dont know what sort of timing was being used at the time. But still 1.75bar on a stock motor is not good. Quote Link to comment Share on other sites More sharing options...
bromy Posted July 1, 2007 Share Posted July 1, 2007 As he said in his reply to the thread he blames the engine and perhaps fueling Would not have thought it would be fueling, them pics of your plugs dont look like they have been running in a lean condition Quote Link to comment Share on other sites More sharing options...

The ceramics can break....but in this case the plugs are in good condition, but the piston is fooked...thus backing up my argument. Quote Link to comment Share on other sites More sharing options...

suprafan72 Posted July 1, 2007 Share Posted July 1, 2007 Come on guys, give the guy a break.. .Nitrous does tend to spike boost as we all know... So i can see Dan's argument in raising the boost for mapping.. its a very difficult one to Judge... We all know there is huge risk in tuning an engine especially with nitrous!!! So a map with 1.5 bar could easily spike to 1.7 bar on a nitrous run?? Quote Link to comment Share on other sites More sharing options...

So a map with 1.5 bar could easily spike to 1.7 bar on a nitrous run?? No, that’s not right at all. The mapper should configure the N02 input after the initial map is done, in no way should it be mapped in such a way that the N02 uncontrollably raised the boost. If it does that, again it comes down to the mapper correctly configuring the N02 control. Quote Link to comment Share on other sites More sharing options...

I've never heard of nitrous spiking the boost...please can you give some examples. Personally I don't believe this to be the case IF the wastegate and EBC are setup correctly.

If it does that, again it comes down to the mapper correctly configuring the N02 control. Its a tough call, I had an N20 Car that i ran nitrous on and it was very difficult to keep maintained steady boost as nitrous does make boost harder to control and set during different ambient temperature conditions....
