You could try a couple things. First, try bringing your WGDC in that 2800 RPM cell down a couple percent. Second, if you're really hitting peak boost at 2800 RPM, change that 2800 RPM value to 2600. This will bring WGDC down before you hit boost. You may lose a tad bit of spool, but if done correctly, the boost will hit and be rock solid.

Thanks for the advice. I spent all day tuning this and now that I'm my 36th revision, my map is much closer to yours, but slightly lower values. Past 3500, my boost is rock solid. But my spool is a little rocky. Sometimes I hit full boost like 2900 sometimes 3100, I'm having a little trouble with consistency. It might be the onramp I'm currently going on or the exact rpm I'm in before I start the pull.

The thing I'm trying to nail down right now is right after I hit full boost, my boost takes a 1 psi dip, then steadies out a little later on.

Since my WGDCs are the lowest at 3200, and I'm trying to hit full boost at 2800, i'll set that row to 2600rpm and see if that smooths it out like you say. I think it's a great idea

here's my log now:

Yeah, here's what my boost and WG looks like with my 18g. Ignore the reference WGDC numbers. The higher boost is from a run recently when I turned up the boost now that it's colder here in MN.

Default boost trim error

Quote:
Tip-in-enrichment (boost error)
This is the extra fuel added to tip in enrichment at a particular boost error (so it's a tip in enrichment enrichment). This will only need to be adjusted if you added larger injectors or a fmic.

1.) For a fmic, set all cells to 0 (the much longer ic piping eliminates the need for this table)
2.) For larget injectors on a tmic, multiply each value by (new injector size / original injector size)
** 2.)is a best guess base on the info from the cobb tuning guide. It's a guess since cobb's fuel multipliers seems to be the inverse of romraiders. The raw ecu values seems to have an inverse relationship with the units used by romraider
.



I believe there is an error about the "tip-in enrichment compensation (boost error)", "Fuel Iinjector Boost Trim Error" in street tuner here

romraider seem to allow -99.22 to 99.22 values in this table

street tuner alows 0-255

looking at both stock tables it seems that -99.22 in romraider would = 0 in street tuner which would = no boost trim compensation

I think that they are liner just different values






using Sreet Tuner and their instructions I rescaled this table fo 650cc injectors from 550 stocks



this is what it ends up as in the same map I pulled with ECU flash




my math is +100*(old/new)= X -100 = (new value)...but thats not right




I am trying to scale this for 1100cc injectors in romraider any one want to do the math .....I'm tired

It appears ST is using the raw ECU value. The conversion from the raw ECU value using RomRaider's conversion would be (x*.78125)-100.

-100 in RomRaider would be 0 raw value.

Also, not that it matters for this table, but you are using old ECU defs. I suggest you update to the latest ECU/logger defs for additional table/parameter/ROM support.

thank you for the math


how did you determine the old defs from the pics ?

Well, they are my defs - so I'm intimately familiar with them.

Since I can't post on the RR forum for some reason....

Can anyone give me an idiots guide on how to use the rescaler tab on Airboys spreadsheet?

Is there any reason why the AFR tab didn't get the same rescaling function that the Ignition Timing table has?

I'm not ungrateful, just wondering.

Thanks,
Paul

Bad Noodle...not sure if it's been mentioned or added yet but you need to add a section explaining how to raise/lower the redline level.

Bad Noodle, think you could post the original google doc or a pdf to make for easier printing? I already made a word doc for myself, but I would have appreciated one so I didn't miss anything...

Hey, I made some mistakes in the original that I corrected in these posts. So the posts are all up to date. I didn't bother updating the original docs, which is why I didn't want to post them.

weird question: when you say you should use a virus free laptop; can a laptop with lots of viruses transfer a virus to the car ecu when loading maps or data logging?

no, but if the virus halts or slows your comp while flashing, you might damage the ecu or completely break it

i cant tell you how much this helped me at the end of last year when i was first getting into tuning my own car. THANK YOU! i have since sent every person that has tuning questions to read this its a great starters guide and i just realized that i should probably thank you for it! and i agree, it should be a sticky, im tired of telling people to search for it or pasting a link
