You have already paid him how much money? How many revisions has he done to get your map where it is now? It most definitely does not require a full out start from scratch tune, he is scamming u big time. I'm sure he could make the revisions to your current tune in 5minutes and have a revised map to you for testing, will review those logs and need to revise a couple more times likely and each revision will take him a few minutes.

All the hard work is done with your car, even if you went with a ps2 setup it would be the same thing for a tuner just a couple revisions to your already good custom tune (however ps2 would require some fueling adjustments in the map along with set point, wgdc, timing, load related items).

Im going to use my current tune and post logs to make sure I am good.

Your current tune wont be mapped for the higher boost in the upper RPM range. I would be careful and keep and eye on STFT's. Maybe do 1 log in 3'rd and post it for review before tooling around town and potentially leaning out/killing your engine.

what higher boost? isn't the new turbo upgrade capable of a few more psi? and his current tune is going to under target that

Do you know if the tune is targeting load or boost? If it's load based and currently not hitting load target in the upper RPM range then the new compressor will increase boost past previous levels.

At the end of the day I bet he'll run just fine and his fuel maps are probably already set aggressively rich in the areas in question, as this is responsible thing to do as a tuner. That being said you don't want to be driving around with 10:1 AFR unknowingly, or worse leaning out.

Just recommending he be smart about it.

I don't know.

You might be able to tell from the logs. The load based tunes usually have actual load closely following target load (just a little bit below it). The boost based tunes usually have a super high load target, actual load is nowhere close. And in the latter case the target boost is usually completely flat (like BM3)

Links don't work, i think you copied them with the "..." truncation to the original link.

It doesn't look like a load based tune to me. Just look at load Act. vs Target.

Here is a MHD log for comparison: https://datazap.me/u/thejeremyman9/4...&data=16-17-25

And a log on completely stock car/tune, which should be load based: https://datazap.me/u/thejeremyman9/s...&data=12-13-19

Do same comparison of actual vs. req.

So do u think I will be fine?

I don't feel comfortable telling you one way or the other, i am just trying to provide my insight. I would echo what ///M248 said above; proceed with caution and be smart about it. I would drive the car around carefully for a little bit, then do some logs. Maybe even a partial throttle log first, take a look, then work you way up to a full WOT log. Maybe even log a lower gear first, that puts less load on everything. If anything looks or feels off, stop. The DME is quite good at protecting the engine, but who knows what Cary changed in the custom tune that could impact that.

I know that each manufacturer uses their own tuning targets and i'm under the impression that BMW uses load and Subaru as an example uses boost targets. I used to use Cobb's Access Tuner Race to self tune my N54 and it was definitely load based tuning, the whole strategy was to achieve a load, not achieve a boost. From my experience with Subaru and BMW tuning, this tuning method is superior to boost based tuning for various reasons. IMO
My 2 cents worth. lol

Yeah but the question here is not about what the manufacturer uses, it's what his cutom tuner uses. Yes, BMW uses load-based tune on the stock map, and MHD continues to use it on their OTS maps, but i believe BM3 going to boost-based tuning, and it appears his tuner does as well.

It's just the first i've heard of it so i was a little surprised. Thinking out loud i feel like load based would be safer, boost based is not as intuitive but might offer more performance. Interesting........

I ended up getting the retune. I've only had one revision so far. Below are logs. The car feels stronger up top.

Did you even attempt to drive/log on the old tune with the new turbo?

What are your first impressions - change in responsiveness/lag? Worth the money?

I only looked at the bottom log, but i find it a little surprising you are still trailing below boost target at 90% WGDC. Could just need some tune refinements though.

Do you have a link to one of your "best" logs from the old custom tune before the turbo? I think putting these logs (or logs once this tune is dialed in) in virtual dyno will really show how much you are benefiting from the turbo upgrade.

A little to no lag and I notice a huge difference from mid to top end. I am happy with it so far. Just waiting to get the tune dialed in.

New logs with dinan turbo. Cary still revising.

Looks like boost is dropping a decent amount up top still even with WGDC in the 90s. Do you think the dinan turbo is going to be able to hold 20+ psi to redline? At least it looks like it spools fast.

There's also a weird throttle closure and whatnot at 6800 in the last log (didnt look at the others).
